I'm not sure if this is the correct fix, but it does seem to allow the
build to complete. I suspect that this was broken by commit 34ed780a6afc
(rtlwifi: Fix problems with building an allyesconfig). Most of the files
that removed the include of pwrseqcmd.h, added one for ../pwrseqcmd.h.
The rtl8188ee driver had it removed it but didn't add the include of the
file in the parent directory.

This fix is certainly OK. What I do not understand is why neither I nor the
build testing computers see the problem. Does this show for all architectures? I
have only built this driver for x86_64.
Thanks,
Larry

I'm a little baffled too as to why it's failing for me. At first I had
assumed that it was temporary breakage, but I've been seeing this fail
to build for a while now (at least a few months). I'm also building on
x86_64 (Fedora 21, fwiw).
Here's a verbose build output of that file without this patch. Maybe
you can spot some difference? It's possible I have something configured
wrong, but everything else seems to build just fine...

I compiled that file using the same command. The only difference in the gcc line
is your system uses "-fstack-protector-strong", and mine uses
"-fno-stack-protector". I think that is caused by a different setting for
CONFIG_CC_STACKPROTECTOR, and is not significant.
I do not see anything that you have wrong. Certainly, the patch is needed.
