This patch fix the modalias when the rtc driver is built
as a module, so the right name is used.
Everything operates correctly when this module is builtin.
I'm sure this used to work. Do you know when/why it broke? Perhaps a Fixes:
tag would be useful, and perhaps a Cc: stable?
I don't remember autoloading of rtc-tps6586x.ko has ever worked. Then
there is still the issue of rtc modules loaded too late for the kernel
(or the kernel not capable to defer the read of hw clock), but that's
another issue.
I first tried to report the issue on this bug tracker and at that
time, autoloading wasn't working (was in 2014).

I'm sure current distros using an arm generic kernel (with all
modules) will rebase on kernel 4.4, but technically the bug is present
in kernel 3.10 from the oldest current maintained branch (since the
driver introduction).
Ah, all the cases I used previous did indeed have the RTC driver
built-in not a module, so that explains it.
