Hi Ulf,
After merging the mmc-uh tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

Yup, sorry for this noise. Arnd had removed a lot of IS_ERR_VALUE
abuses, but I forgot to amend this one.
Hi Ulf,
Should I come up with a new fix or you could manually amend it from
"IS_ERR_VALUE(err)" to "err < 0"? :)
Introduced by commit
8141f0ace818 ("mmc: core: implement enhanced strobe support")
I think error values now must be "long".
