pm2fb: Permedia 2V initialization fixes
This patch: - initializes correctly the Permedia2V chip if it is not initialized by BIOS - puts back clock frequency for the ELSA WINNER board to 100kHz - fixes returned error values from setcolreg() function - uses more general classes for PCI ids Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
