Subject: cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call
X-Git-Tag: omap-for-v3.19/fixes-rc1~125^2~5
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=666224d4d582661e3c7d321c23e8c69e4068ee55

cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call

Remove use of calls into t4_fw_hello() with MASTER_MUST, which results in
FW_HELLO_CMD_MASTERFORCE being set. The firmware doesn't support this and of
course any existing PF Drivers will totally go for a toss.
