Subject: drm/radeon/atom: fix typo in SetPixelClock handling
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e729586e33593cd11112ff22fa8f0e801af05b4e;p=linux-beck.git

drm/radeon/atom: fix typo in SetPixelClock handling

MiscInfo field should be programmed with the crtc id
rather than the pll id.  However, at this point the
two are the same for chips with this version of the table.
