Subject: [PATCH] rt2x00: Remove rt2x00_clear_link
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8de8c5162b157884aa4855564cbfd9ec9119c819;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[PATCH] rt2x00: Remove rt2x00_clear_link

rt2x00_clear_link() was becoming too large for statically inline,
also it was used on a single location and shouldn't really be
used anywhere else. So move the entire code into the function
rt2x00lib_start_link_tuner()
