treewide: Replace open-coded flex arrays in unions

2021-10-18T19:28:53Z

In support of enabling -Warray-bounds and -Wzero-length-bounds and correctly handling run-time memcpy() bounds checking, replace all open-coded flexible arrays (i.e. 0-element arrays) in unions with the DECLARE_FLEX_ARRAY() helper macro. This fixes warnings such as: fs/hpfs/anode.c: In function 'hpfs_add_sector_to_btree': fs/hpfs/anode.c:209:27: warning: array subscript 0 is outside the bounds of an interior zero-length array 'struct bplus_internal_node[0]' [-Wzero-length-bounds] 209 | anode->btree.u.internal[0].down = cpu_to_le32(a); | ~~~~~~~~~~~~~~~~~~~~~~~^~~ In file included from fs/hpfs/hpfs_fn.h:26, from fs/hpfs/anode.c:10: fs/hpfs/hpfs.h:412:32: note: while referencing 'internal' 412 | struct bplus_internal_node internal[0]; /* (internal) 2-word entries giving | ^~~~~~~~ drivers/net/can/usb/etas_es58x/es58x_fd.c: In function 'es58x_fd_tx_can_msg': drivers/net/can/usb/etas_es58x/es58x_fd.c:360:35: warning: array subscript 65535 is outside the bounds of an interior zero-length array 'u8[0]' {aka 'unsigned char[]'} [-Wzero-length-bounds] 360 | tx_can_msg = (typeof(tx_can_msg))&es58x_fd_urb_cmd->raw_msg[msg_len]; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/net/can/usb/etas_es58x/es58x_core.h:22, from drivers/net/can/usb/etas_es58x/es58x_fd.c:17: drivers/net/can/usb/etas_es58x/es58x_fd.h:231:6: note: while referencing 'raw_msg' 231 | u8 raw_msg[0]; | ^~~~~~~ Cc: "Gustavo A.

Revert "ALSA: uapi: Drop asound.h inclusion from asoc.h"

2020-03-31T09:01:12Z

This reverts commit 645c08f17f477915f6d900b767e789852f150054 which was reported to break the build a program using this header. The original issue was addressed in the alsa-lib side recently, so we can make the header more self-contained again. Reported-by: Dmitry V.

ALSA: uapi: Drop asound.h inclusion from asoc.h

2019-12-20T15:45:12Z

The asound.h isn't always available while asoc.h itself is distributed in alsa-lib package. So we need to avoid the unnecessary inclusion of asound.h from there. Link: https://lore.kernel.org/r/20191220153415.2740-6-tiwai@suse.de Signed-off-by: Takashi Iwai

ASoC: topology: Add definitions for mclk_direction values

2018-04-16T16:52:31Z

Current comment makes not clear the direction of mclk. Previously, similar description caused a misunderstanding for bclk_master and fsync_master. This commit solves the potential confusion the same way it is solved for bclk_master and fsync_master.

ASoC: topology: Add missing clock gating parameter when parsing hw_configs

2018-04-16T16:52:26Z

Clock gating parameter is a part of `dai_fmt`. It is supported by `alsa-lib` when creating a topology binary file, but ignored by kernel when loading this topology file. After applying this commit, the clock gating parameter is not ignored any more. This solution is backwards compatible. The existing behaviour is not broken, because by default the parameter value is 0 and is ignored. snd_soc_tplg_hw_config.clock_gated = 0 => no effect snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT For example, the following config, based on alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported: ~~~~ SectionHWConfig."CodecHWConfig" { id "1" format "I2S" # physical audio format. pm_gate_clocks "true" # clock can be gated } SectionLink."Codec" { # used for binding to the physical link id "0" hw_configs [ "CodecHWConfig" ] default_hw_conf_id "1" } ~~~~ Signed-off-by: Kirill Marinushkin Reviewed-by: Pierre-Louis Bossart Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Mark Brown Cc: Pan Xiuli Cc: Liam Girdwood Cc: linux-kernel@vger.kernel.org Cc: alsa-devel@alsa-project.org Signed-off-by: Mark Brown

ASoC: topology: Fix bclk and fsync inversion in set_link_hw_format()

2018-04-16T16:52:16Z

The values of bclk and fsync are inverted WRT the codec. But the existing solution already works for Broadwell, see the alsa-lib config: `alsa-lib/src/conf/topology/broadwell/broadwell.conf` This commit provides the backwards-compatible solution to fix this misuse.

License cleanup: add SPDX license identifier to uapi header files with a license

2017-11-02T10:20:11Z

Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.
