2022-09-03pinctrl: at91: use dev_dbg() instead of printk()Claudiu Beznea1-2/+2
Use dev_dbg() instead of printk(KERN_DEBUG) to avoid the following checkpatch.pl warning: "Prefer [subsystem eg: netdev]_dbg([subsystem]dev, ... then dev_dbg(dev, ... then pr_debug(... to printk(KERN_DEBUG ...".

2022-09-03pinctrl: at91: move gpio suspend/resume calls to driver's contextClaudiu Beznea3-74/+36
Move gpio suspend/resume execution local to driver and let it execute as close as possible to the moment the machine specific PM code is executed (by setting it to .noirq member of dev_pm_ops). With this the at91_pinctrl_gpio_suspend()/at91_pinctrl_gpio_resume() calls were removed from arch/arm/mach-at91/pm.c and also a header has been removed. The patch has been checked on sama5d3_xplained, sam9x60ek, sama5d2_xplained, sama7g5ek boards.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König619-1733/+646
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

A remove callback that just returns 0 is equivalent to no callback at all as can be seen in i2c_device_remove(). So simplify accordingly. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Wolfram Sang <wsa@kernel.org>

2022-08-14afs: Enable multipage folio supportDavid Howells2-1/+3
Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.
