Alan Curry db77ec270d [PATCH] framebuffer: cmap-setting return values 
A set of 3 small bugfixes, all of which are related to bogus return values
of fb colormap-setting functions.

First, fb_alloc_cmap returns -1 if memory allocation fails. This is a hard
condition to reproduce since you'd have to be really low on memory, but from
studying the contexts in which it is called, I think this function should be
returning a negative errno, and the -1 will be seen as an EPERM. Switching it
to -ENOMEM makes sense.

Second, the store_cmap function which is called for writes to
/sys/class/graphics/fb0/color_map returns 0 for success, but it should be
returning the count of bytes written since its return value ends up in
userspace as the result of the write() syscall.

Third, radeonfb returns 1 instead of a negative errno when FBIOPUTCMAP is
called with an oversized colormap.  This is seen in userspace as a return
value of 1 from the ioctl() syscall with errno left unchanged.  A more
useful return value would be -EINVAL.
