video: fbdev: aty: Fix set but not used warnings in mach64_ct
Fix W=1 warnings about variables assigned but never used. - One variable is only used when CONFIG_FB_ATY_GENERIC_LCD is defined Fix so variable is only defined with CONFIG_FB_ATY_GENERIC_LCD - Several variables was only assigned by a call to aty_ld_le32(). Drop the variables but keep the call to aty_ld_le32() as it may have unexpected side-effects. v2: - Updated subject (Lee) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Lee Jones <lee.jones@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201128224114.1033617-7-sam@ravnborg.org
