Subject: s390/setup: Add decompressor_handled_param() wrapper
X-Git-Tag: v6.15-rc1~113^2~38
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=66ec751719d62c5c5eb7143af0a48e93ec079b5e;p=thirdparty%2Fkernel%2Flinux.git

s390/setup: Add decompressor_handled_param() wrapper

Make decompressor_handled_param() a wrapper for
__decompressor_handled_param(). __decompressor_handled_param() now
takes two parameters: a function name and a parameter name, which do
not necessarily match.

This allows to use characters like "-", which are not allowed in
function names, for command line parameters which are handled by the
decompressor and should be ignored by the kernel.
