When ufshcd_rtc_work calls ufshcd_rpm_put_sync and the pm's
usage_count is 0, it will enter the runtime suspend callback.
However, the runtime suspend callback will wait to flush
ufshcd_rtc_work, causing a deadlock.
Replacing ufshcd_rpm_put_sync with ufshcd_rpm_put can avoid
the deadlock.

No blank lines in the tags section please. Additionally, a hash sign
(#) is missing between "<stable@xxxxxxxxxxxxxxx>" and "6.11.x".
Otherwise this patch looks good to me. Hence:
