From: Andrei Warkentin Date: Sat, 24 Sep 2011 16:12:30 +0000 (-0400) Subject: mmc: core: ext_csd.raw_* used in comparison but never set X-Git-Tag: firefly_0821_release~7541^2~2537 X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c359836591a99d43c5e4c6792de75dcaddee805e;p=firefly-linux-kernel-4.4.55.git mmc: core: ext_csd.raw_* used in comparison but never set commit 5238acbe36dd5100fb6b035a995ae5fc89dd0708 upstream. f39b2dd9d ("mmc: core: Bus width testing needs to handle suspend/resume") added code to only compare read-only ext_csd fields in bus width testing code, yet it's comparing some fields that are never set. The affected fields are ext_csd.raw_erased_mem_count and ext_csd.raw_partition_support.
