When I updated my tree (via bk cvs gateway) to make the patch I noticed
some changes in sysfs's binary support.
In general, they look good, but the size of files is set in
sysfs_create_bin_file and not changeable later. This breaks
firmware_class.c :(
With current request_firmware(), the drivers don't tell the size of the
firmware, and in some cases they don't even know, so changing the
interface is no good.
I also don't understand why sysfs needs to keep a copy of the data in
it's own buffer. It has to ask the driver for any read/write anyway,
the previous approach of one page at a time looked better to me and
saves some kernel memory :-).
And the size checks could be skipped in case of zero size.
I'll include a change proposal to sysfs/bin.c next time.
Have a nice day
Manuel
