commit40ce1121c1upstream. commitf86c3ed559("drm/mgag200: Split PLL setup into compute and update functions") introduced a regression for g200wb and g200ew. The PLLs are not set up properly, and VGA screen stays black, or displays "out of range" message. MGA1064_WB_PIX_PLLC_N/M/P was mistakenly replaced with MGA1064_PIX_PLLC_N/M/P which have different addresses. Patch tested on a Dell T310 with g200wb Fixes:f86c3ed559("drm/mgag200: Split PLL setup into compute and update functions") Cc: stable@vger.kernel.org Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20220308174321.225606-1-jfalempe@redhat.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
