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.

I thought that I got rid of all the unused variables but somehow
I missed these. Sorry and thanks a lot for taking care of this.

Where's your diffstat?

By the way, someone sent a patch to fix these 20 mins before you
did. :)
