Subject: env: Drop the double underscores in search.h
X-Git-Tag: v2019.10-rc2~4^2~5
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cb2ba9db5f2ab575d40d95e76a0ab94c7ccb9bac;p=oweals%2Fu-boot.git

env: Drop the double underscores in search.h

There doesn't seem to be any good reason for using __ in the arguments in
this header file. A double underscore is usually reserved for compiler
features.

Drop these and remove the unnecessary 'extern' as well.
