mips: sgi-ip22: Drop redundant check from .remove()

2022-07-05T09:10:17Z

The remove callback is only called by the driver core if there is a driver to unbind, so there is no need to check dev->driver to be non-NULL. Signed-off-by: Uwe Kleine-König Signed-off-by: Thomas Bogendoerfer

mips: ip22: Reword PANICED to PANICKED and remove useless header

2022-05-04T20:23:56Z

Many other place in the kernel prefer the latter, so let's keep it consistent in MIPS code as well. Also, removes a useless header. Cc: Thomas Bogendoerfer Signed-off-by: Guilherme G. Piccoli Signed-off-by: Thomas Bogendoerfer

mips: sgi-ip22: add a check for the return of kzalloc()

2022-03-30T18:25:11Z

kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check it to prevent potential wrong memory access. Signed-off-by: Xiaoke Wang Signed-off-by: Thomas Bogendoerfer

MIPS: SGI-IP22: Remove unnecessary check of GCC option

2021-12-14T09:02:40Z

According to Documentation/process/changes.rst, the minimal version of GCC is 5.1, and -mr10k-cache-barrier=store is supported with GCC 5.1 [1], just remove the unnecessary check to fix the build error [2]: arch/mips/sgi-ip22/Platform:28: *** gcc doesn't support needed option -mr10k-cache-barrier=store.

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.

bus: Make remove callback return void

2021-07-21T09:53:42Z

The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

kernel.h: split out panic and oops helpers

2021-07-01T18:06:04Z

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35Z

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot of which one was reported by Thomas Bogendoerfer as well. There were a few more issues including build errors, those also have been fixed.
