mfd: avoid newly introduced compiler warning
Commit b158b69a3765 ("mfd: rtsx: Simplify function return logic")
removed the use of the 'err' variable, but left the variable itself
around, resulting in gcc quite reasonably warning:
drivers/mfd/rtsx_pcr.c: In function ‘rtsx_pci_set_pull_ctl’:
drivers/mfd/rtsx_pcr.c:565:6: warning: unused variable ‘err’ [-Wunused-variable]
int err;
^
Get rid of the unused variable, and avoid the new warning.
