mtd: Switch back to struct platform_driver::remove()

2024-10-21T09:58:07Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/mtd to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

mtd: maps: pxa2xx-flash: Convert to platform remove callback returning void

2023-10-16T08:56:48Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

ARM: pxa: split up mach/hardware.h

2022-04-19T14:27:05Z

The mach/hardware.h is included in lots of places, and it provides three different things on pxa: - the cpu_is_pxa* macros - an indirect inclusion of mach/addr-map.h - the __REG() and io_pv2() helper macros Split it up into separate and mach/pxa-regs.h headers, then change all the files that use mach/hardware.h to include the exact set of those three headers that they actually need, allowing for further more targeted cleanup. linux/soc/pxa/cpu.h can remain permanently exported and is now in a global location along with similar headers. pxa-regs.h and addr-map.h are only used in a very small number of drivers now and can be moved to arch/arm/mach-pxa/ directly when those drivers are to pass the necessary data as resources.

mtd: pxa2xx-flash: switch back from memremap to ioremap_cached

2016-04-04T08:26:40Z

This reverts commit 06968a54790d ("mtd: pxa2xx-flash: switch from ioremap_cache to memremap"), since NOR with memory semantics in array mode and RAM are not necessarily the same thing, and architectures may implement ioremap_cached() and memremap() with different memory attributes. For this reason, ioremap_cached() has been brought back from the dead on the ARM side, so switch this driver back to using it instead of memremap().
