The problem is probably present with the other cards but since I could not validate or test the patch with them, I have left them unchanged. If you were to determine that it apply to all of them then maybe the patch could be moved to ps.c to wrap hw_init() call. > > The changes are certainly minimal; however, I do need to test them before giving > my Ack. > > As the problem(s) fixed by this patch will affect stable kernels, you should add > a "Cc: Stable " patch. > > Originally, I was going to have you add a comment to the commit message on why > you were changing the return value in rtl_ps_enable_nic(), but now I am thinking > that this should be a separate commit as it fixes a totally different bug.
