Simon Ser 26297e1710 drm/fourcc: fix Amlogic format modifier masks ... [ Upstream commit cc3283f8f41f741fbaef63d0503d8fb4a7919100 ] The comment says the layout and options use 8 bits, and the shift uses 8 bits. However the mask is 0xf, ie. 0b00001111 (4 bits). This could be surprising when introducing new layouts or options that take more than 4 bits, as this would silently drop the high bits. Make the masks consistent with the comment and the shift. Found when writing a drm_info patch [1].
