Subject: mmc: omap_hsmmc: release correct resource
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=48b332f9916f33ba0001b78e5cea49ef17f3c81e;p=linux-beck.git

mmc: omap_hsmmc: release correct resource

res can be one of several resources, as this variable is re-used several
times during probe.  This can cause the wrong resource parameters to be
passed to release_mem_region().

Get the original memory resource before calling release_mem_region().
