Subject: arm64: irqflags: Add condition flags to inline asm clobber list
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f57065782f245ca96f1472209a485073bbc11247;p=openwrt%2Fstaging%2Fblogic.git

arm64: irqflags: Add condition flags to inline asm clobber list

Some of the inline assembly instruction use the condition flags and need
to include "cc" in the clobber list.
