Subject: nds32: Remove the redundant assignment
X-Git-Tag: v5.15~7296^2~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2e95c4d672ce6c931951c87b5dbfa4106fd3cae6;p=platform%2Fkernel%2Flinux-starfive.git

nds32: Remove the redundant assignment

For early version, the value of r2 register was used to display
a character on UART when error occurred. Remove these r2 assignments
because we no longer show the character.
