Subject: [SCSI] qla2xxx: Always (re)read firmware version/capabilities information.
X-Git-Tag: v2.6.30-rc1~185^2~63
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dda772e8e3b9832d3368f84df3a3b7ec7dfbd9f0;p=karo-tx-linux.git

[SCSI] qla2xxx: Always (re)read firmware version/capabilities information.

With recent ISPs loading firmware from flash, a flash-update to
the firmware-image region with a follow-on reset will reload the
new image.

Original caching of data only made sense when firmware was bound
with the driver.
