Subject: iwlwifi: move uCode flags handling to op_mode
X-Git-Tag: v3.12-rc1~3664^2~108^2~241
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a78be210d53b24cc3437d4362912c510b895a8eb;p=kernel%2Fkernel-generic.git

iwlwifi: move uCode flags handling to op_mode

The uCode flags modification is op_mode dependent
since the P2P config is an op-mode config.

This also fixes P2P enabling: due to the uCode
loading code shuffle moving the SKU check before
the EEPROM was read it was always false and would
always disable PAN/P2P.
