rtc: add missing MODULE_DESCRIPTION() macro

On x86, make allmodconfig && make W=1 C=1 reports: WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/rtc/lib_test.o WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/rtc/rtc-goldfish.o WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/rtc/rtc-omap.o WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/rtc/rtc-rc5t583.o WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/rtc/rtc-tps65910.o WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/rtc/rtc-twl.o Add the missing invocation of the MODULE_DESCRIPTION() macro to all files which have a MODULE_LICENSE(). This includes rtc-mpc5121.c, which does not produce a warning with the x86 allmodconfig since it is not built for x86, but it may cause this warning with Freescale PPC configurations.

rtc: twl: remove unnecessary messages

2023-09-05T23:26:04+00:00

The RTC core already prints a message when the RTC is registered and when registering fails, it is not necessary to have more in the driver. Link: https://lore.kernel.org/r/20230827221643.544259-2-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: twl: Convert to platform remove callback returning void

2023-03-17T22:03:18+00:00

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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

rtc: twl: make driver DT only

2016-11-30T20:21:33+00:00

Since there are no platform based users and all users of this code are TI OMAP-based which is DT only, it makes sense to remove unused code. Signed-off-by: Nicolae Rosia Tested-by: Tony Lindgren Signed-off-by: Alexandre Belloni

rtc: twl: kill static variables

2016-11-30T20:21:01+00:00

The current code uses static variables which prevent the use of multiple rtc twl instances. We also make it clear that this driver supports only TWL4030 and TWL6030 classes. Signed-off-by: Nicolae Rosia Tested-by: Tony Lindgren Signed-off-by: Alexandre Belloni

rtc: constify rtc_class_ops structures

2016-09-01T23:24:06+00:00

Check for rtc_class_ops structures that are only passed to devm_rtc_device_register, rtc_device_register, platform_device_register_data, all of which declare the corresponding parameter as const. Declare rtc_class_ops structures that have these properties as const. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct rtc_class_ops i@p = { ... }; @ok@ identifier r.i; expression e1,e2,e3,e4; position p; @@ ( devm_rtc_device_register(e1,e2,&i@p,e3) | rtc_device_register(e1,e2,&i@p,e3) | platform_device_register_data(e1,e2,e3,&i@p,e4) ) @bad@ position p != {r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct rtc_class_ops i = { ... }; // Signed-off-by: Julia Lawall Acked-by: Baruch Siach Acked-by: Hans Ulli Kroll Acked-by: Linus Walleij Acked-by: Thierry Reding Signed-off-by: Alexandre Belloni
