Subject: Bluetooth: btqca: move WCN7850 workaround to the caller
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff3bb47ab4ca4f3bac5f680d63456353892b4500;p=thirdparty%2Fkernel%2Flinux.git

Bluetooth: btqca: move WCN7850 workaround to the caller

WCN7850 will first attempt to use ELF_TYPE_PATCH,
and if that fails, it will fall back to TLV_TYPE_PATCH.

To code uniformity, move WCN7850 workaround to the caller.
