Subject: csky: remove BS check for FAULT_FLAG_ALLOW_RETRY
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9892775af5a5323a7f15ae1d92d025b5be14c658;p=users%2Fhch%2Fmisc.git

csky: remove BS check for FAULT_FLAG_ALLOW_RETRY

flags are initialized as FAULT_FLAG_DEFAULT, and the only thing done
to that afterwards is |=; since FAULT_FLAG_DEFAULT already includes
FAULT_FLAG_ALLOW_RETRY, it's guaranteed to remain there all along.
