Clang warns when multiple pairs of parentheses are used for a single conditional statement.
drivers/video/fbdev/sis/init301.c:851:42: warning: equality comparison with extraneous parentheses [-Wparentheses-equality] } else if((SiS_Pr->SiS_IF_DEF_LVDS == 1) /* || ~~~~~~~~~~~~~~~~~~~~~~~~^~~~ drivers/video/fbdev/sis/init301.c:851:42: note: remove extraneous parentheses around the comparison to silence this warning } else if((SiS_Pr->SiS_IF_DEF_LVDS == 1) /* || ~ ^ ~ drivers/video/fbdev/sis/init301.c:851:42: note: use '=' to turn this equality comparison into an assignment } else if((SiS_Pr->SiS_IF_DEF_LVDS == 1) /* || ^~ = 1 warning generated.
Remove the parentheses and while we're at it, clean up the commented code, which has been here since the beginning of git history.
