Subject: [PATCH] mfd: remove unused variables

A mass-cleanup by Javier Martinez Canillas removed a lot of
unused code, but left at least two variables in mfd drivers
in place that are now causing warnings:

drivers/mfd/rtsx_pcr.c: In function 'rtsx_pci_set_pull_ctl':
drivers/mfd/rtsx_pcr.c:564:6: warning: unused variable 'err' [-Wunused-variable]
drivers/mfd/lm3533-core.c: In function 'lm3533_i2c_probe':
drivers/mfd/lm3533-core.c:595:6: warning: unused variable 'ret' [-Wunused-variable]

This removes them as well.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: c749db571dc ("mfd: lm3533: Simplify function return logic")
Fixes: a3c29b09982 ("mfd: rtsx: Simplify function return logic")
