Avoid accessing directly rtc->ops_lock and use the RTC core helpers.

faac910201 rtc: Remove dev_err() usage after platform_get_irq()
We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).

aa156c8aee rtc: asm9260: fix module autoload
If the driver is built as a module, autoload won't work because the module
alias information is not filled so user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/rtc/rtc-asm9260.ko | grep alias
$

After this patch:

$ modinfo drivers/rtc/rtc-asm9260.ko | grep alias
alias:          of:N*T*Calphascale,asm9260-rtcC*
alias:          of:N*T*Calphascale,asm9260-rtc

de75ccdd41 rtc: asm9260: rework locking
The rtc-asm9260 driver uses a discrete spinlock (wrongly uninitialized).
Use the rtc mutex to lock mmio accesses instead.

15c6ea6f81 rtc: asm9260: remove incorrect __init/__exit annotations
The probe and remove callbacks of the platform driver are marked __init
and __exit, respectively. However, this is not a correct way to annotate
them, as it will result in those sections to be discarded at link time
or after boot, while we can actually call them again based on manual
unbinding, or deferred probing.

Kbuild warns about the problem:

WARNING: drivers/rtc/rtc-asm9260.o(.data+0x0): Section mismatch in reference from the variable asm9260_rtc_driver to the function .init.text:asm9260_rtc_probe()

This removes the annotations, so we no longer branch into missing
code and avoid the warning.
