Subject: platform/x86: wmi: use !p to check for NULL
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6e0bc588a0842dd740cb692d1398a48a26ed112c;p=linux.git

platform/x86: wmi: use !p to check for NULL

Other parts of the code use the `!p` idiom to check
for NULL pointers, convert `find_guid_context()` to
do the same.
