* MIPS: ip22-gio: Make ip22_gio_set_64bit() and ip22_gio_init() staticGenjian Zhang2024-06-111-2/+2
| | | | | | | | | | | | These functions are used in only one file. Made them static to fix the following build error: arch/mips/sgi-ip22/ip22-gio.c:249:6: error: no previous prototype for ‘ip22_gio_set_64bit’ [-Werror=missing-prototypes] arch/mips/sgi-ip22/ip22-gio.c:398:12: error: no previous prototype for ‘ip22_gio_init’ [-Werror=missing-prototypes] Reported-by: k2ci <kernel-bot@kylinos.cn> Signed-off-by: Genjian Zhang <zhanggenjian@kylinos.cn> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
* mips: sgi-ip22: make gio_bus_type constRicardo B. Marliere2024-02-201-2/+2
| | | | | | | | | | | Now that the driver core can properly handle constant struct bus_type, move the gio_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

* driver core: make struct bus_type.uevent() take a const *Greg Kroah-Hartman2023-01-271-2/+2
| | | | | | | | | | | | The uevent() callback in struct bus_type should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

* mips: sgi-ip22: Drop redundant check from .remove()Uwe Kleine-König2022-07-051-1/+1
| | | | | | | | | 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 <u.kleine-koenig@pengutronix.de> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
* mips: sgi-ip22: add a check for the return of kzalloc()Xiaoke Wang2022-03-301-0/+2
| | | | | | | | | 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.

* bus: Make remove callback return voidUwe Kleine-König2021-07-211-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | The dev_attrs field has long been "depreciated" and is finally being removed, so move the driver to use the "correct" dev_groups field instead for struct bus_type.

* MIPS: ip22-gio: Remove legacy suspend/resume supportLars-Peter Clausen2015-02-201-24/+0
| | | | | | | | | | | | | | | | There are currently no gio device drivers that implement suspend/resume and this patch removes the bus specific legacy suspend and resume callbacks. This will allow us to eventually remove struct bus_type legacy suspend and resume support altogether. gio device drivers wanting to implement suspend and resume can use dev PM ops which will work out of the box without further modifications necessary.
