spi: Fix null dereference on suspend

2023-11-28T17:19:55Z

commit bef4a48f4ef798c4feddf045d49e53c8a97d5e37 upstream. A race condition exists where a synchronous (noqueue) transfer can be active during a system suspend. This can cause a null pointer dereference exception to occur when the system resumes. Example order of events leading to the exception: 1. spi_sync() calls __spi_transfer_message_noqueue() which sets ctlr->cur_msg 2. Spi transfer begins via spi_transfer_one_message() 3. System is suspended interrupting the transfer context 4. System is resumed 6. spi_controller_resume() calls spi_start_queue() which resets cur_msg to NULL 7. Spi transfer context resumes and spi_finalize_current_message() is called which dereferences cur_msg (which is now NULL) Wait for synchronous transfers to complete before suspending by acquiring the bus mutex and setting/checking a suspend flag.

mtd: spi-nor: avoid holes in struct spi_mem_op

2023-07-27T14:54:22Z

gcc gets confused when -ftrivial-auto-var-init=pattern is used on sparse bit fields such as 'struct spi_mem_op', which caused the previous false positive warning about an uninitialized variable: drivers/mtd/spi-nor/spansion.c: error: 'op' is used uninitialized [-Werror=uninitialized] In fact, the variable is fully initialized and gcc does not see it being used, so the warning is entirely bogus. The problem appears to be a misoptimization in the initialization of single bit fields when the rest of the bytes are not initialized. A previous workaround added another initialization, which ended up shutting up the warning in spansion.c, though it apparently still happens in other files as reported by Peter Foley in the gcc bugzilla. The workaround of adding a fake initialization seems particularly bad because it would set values that can never be correct but prevent the compiler from warning about actually missing initializations. Revert the broken workaround and instead pad the structure to only have bitfields that add up to full bytes, which should avoid this behavior in all drivers. I also filed a new bug against gcc with what I found, so this can hopefully be addressed in future gcc releases. At the moment, only gcc-12 and gcc-13 are affected.

backlight: corgi_lcd: fix missing prototype

2023-07-27T13:39:17Z

The corgi_lcd_limit_intensity() function is called from platform and defined in a driver, but the driver does not see the declaration: drivers/video/backlight/corgi_lcd.c:434:6: error: no previous prototype for 'corgi_lcd_limit_intensity' [-Werror=missing-prototypes] 434 | void corgi_lcd_limit_intensity(int limit) Move the prototype into a header that can be included from both sides to shut up the warning.

spi: Use struct_size() helper

2023-07-14T13:44:39Z

The Documentation/process/deprecated.rst suggests to use flexible array members to provide a way to declare having a dynamically sized set of trailing elements in a structure.This makes code robust agains bunch of the issues described in the documentation, main of which is about the correctness of the sizeof() calculation for this data structure. Due to above, prefer struct_size() over open-coded versions.
