MIPS: SGI-IP27: Fix platform-device leak in bridge_platform_create()

2022-09-19T14:33:27Z

In error case in bridge_platform_create after calling platform_device_add()/platform_device_add_data()/ platform_device_add_resources(), release the failed 'pdev' or it will be leak, call platform_device_put() to fix this problem. Besides, 'pdev' is divided into 'pdev_wd' and 'pdev_bd', use platform_device_unregister() to release sgi_w1 resources when xtalk-bridge registration fails.

MIPS: SGI-IP27: Free some unused memory

2022-04-26T13:06:00Z

platform_device_add_data() duplicates the memory it is passed. So we can free some memory to save a few bytes that would remain unused otherwise. Signed-off-by: Christophe JAILLET Signed-off-by: Thomas Bogendoerfer

MIPS: Allow modules to set board_be_handler

2021-11-09T15:07:26Z

After making the brcmstb_gisb driver modular with 707a4cdf86e5 ("bus: brcmstb_gisb: Allow building as module") Guenter reported that mips allmodconfig failed to link because board_be_handler was referenced. Thomas indicated that if we were to continue making the brcmstb_gisb driver modular for MIPS we would need to introduce a function that allows setting the board_be_handler and export that function towards modules. This is what is being done here: board_be_handler is made static and is now settable with a mips_set_be_handler() function which is exported.

memblock: allow to specify flags with memblock_add_node()

2021-11-06T20:30:42Z

We want to specify flags when hotplugging memory. Let's prepare to pass flags to memblock_add_node() by adjusting all existing users. Note that when hotplugging memory the system is already up and running and we might have concurrent memblock users: for example, while we're hotplugging memory, kexec_file code might search for suitable memory regions to place kexec images. It's important to add the memory directly to memblock via a single call with the right flags, instead of adding the memory first and apply flags later: otherwise, concurrent memblock users might temporarily stumble over memblocks with wrong flags, which will be important in a follow-up patch that introduces a new flag to properly handle add_memory_driver_managed().
