This the kind of patch that doesn't make much sense upstream. Granted, the
files weren't properly named, but there's not requirement upstream that
denies naming two different files with the same name.
Btw, looking at both, it seems that they can be merged: both defines the jpeg
header. The basic difference is that, while gspca jpeg header can have a size of
either 556 or 589 bytes, the one at solo6x10 has 575 bytes.
IMHO, the proper fix is to make solo6x10 driver to use the gspca jpeg.h header.
Assuming that this driver would find his way out of staging, then the jpeg.h
file should also be moved to another place, like include/linux/media, as I
don't think that solo6x10 driver should be a gspca sub-driver.
Hans G, what do you think?

Hmm.. probably they're using "=" or ":=" instead of "+=". While this works at
leaf Makefiles, this breaks compilation when there's just one Makefile, or
when you add another thing to be compiled there. This is something that requires
a fix.
