2023-10-13phy: realtek: Replace of_device.h with explicit includesRob Herring2-2/+2
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other and pull in various other headers. In preparation to fix this, adjust the includes for what is actually needed. of_device.h isn't needed, but platform_device.h was implicitly included by it.

2023-09-21phy: realtek: usb: Drop unnecessary error check for debugfs_create_dir()Jinjie Ruan2-16/+4
Both debugfs_create_dir() and debugfs_create_file() return ERR_PTR and never return NULL. As Greg suggested, this patch removes the error checking for debugfs_create_dir in phy-rtk-usb2.c and phy-rtk-usb3.c. This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary.

2023-09-14phy: mapphone-mdm6600: Fix pinctrl_pm handling for sleep pinsTony Lindgren1-17/+12
Looks like the driver sleep pins configuration is unusable. Adding the sleep pins causes the usb phy to not respond. We need to use the default pins in probe, and only set sleep pins at phy_mdm6600_device_power_off(). As the modem can also be booted to a serial port mode for firmware flashing, let's make the pin changes limited to probe and remove. For probe, we get the default pins automatically. We only need to set the sleep pins in phy_mdm6600_device_power_off() to prevent the modem from waking up because the gpio line glitches. If it turns out that we need a separate state for phy_mdm6600_power_on() and phy_mdm6600_power_off(), we can use the pinctrl idle state.

2023-09-09iov_iter: Fix iov_iter_extract_pages() with zero-sized entriesDavid Howells1-15/+15
iov_iter_extract_pages() doesn't correctly handle skipping over initial zero-length entries in ITER_KVEC and ITER_BVEC-type iterators. The problem is that it accidentally reduces maxsize to 0 when it skipping and thus runs to the end of the array and returns 0. Fix this by sticking the calculated size-to-copy in a new variable rather than back in maxsize.

2023-09-09sh: push-switch: Reorder cleanup operations to avoid use-after-free bugDuoming Zhou1-1/+1
The original code puts flush_work() before timer_shutdown_sync() in switch_drv_remove(). Although we use flush_work() to stop the worker, it could be rescheduled in switch_timer(). As a result, a use-after-free bug can occur. The details are shown below: (cpu 0) | (cpu 1) switch_drv_remove() | flush_work() | ... | switch_timer // timer | schedule_work(&psw->work) timer_shutdown_sync() | ... | switch_work_handler // worker kfree(psw) // free | | psw->state = 0 // use This patch puts timer_shutdown_sync() before flush_work() to mitigate the bugs. As a result, the worker and timer will be stopped safely before the deallocate operations. Fixes: 9f5e8eee5cfe ("sh: generic push-switch framework.")

2023-09-09media: dvb: symbol fixup for dvb_attach()Greg Kroah-Hartman106-113/+113
In commit 9011e49d54dc ("modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted to GPL-only marked symbols. This interacts oddly with the DVB logic which only uses dvb_attach() to load the dvb driver which then uses symbol_get(). Fix this up by properly marking all of the dvb_attach attach symbols as EXPORT_SYMBOL_GPL().

2023-09-08Revert "PCI: Mark NVIDIA T4 GPUs to avoid bus reset"Bjorn Helgaas1-1/+1
This reverts commit d5af729dc2071273f14cbb94abbc60608142fd83. d5af729dc207 ("PCI: Mark NVIDIA T4 GPUs to avoid bus reset") avoided Secondary Bus Reset on the T4 because the reset seemed to not work when the T4 was directly attached to a Root Port. But NVIDIA thinks the issue is probably related to some issue with the Root Port, not with the T4. The T4 provides neither PM nor FLR reset, so masking bus reset compromises this device for assignment scenarios. Revert d5af729dc207 as requested by Wu Zongyong. This will leave SBR broken in the specific configuration Wu tested, as it was in v6.5, so Wu will debug that further.
