Subject[PATCH] kernel 2.4.18 endianness logical mistakes correction on fbcon-cfb2.c and fbcon-cfb4.c
Date
DESCRIPTIONS:

2 small patchs to apply to:

drivers\video\fbcon-cfb2.c
drivers\video\fbcon-cf4.c o

This patchs correct the endianness logical of nibbletab, the first table is
u_char mades so no endian needed and the second swap correctly bytes in
LITTLE_ENDIAN. (old version swap half bytes instead of bytes).
