Subject: qla4xxx: Initialize hardware queue for ISP40XX
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aa6db9b9cdf642b220f2a0861facf6bab1d3ab37;p=linux-beck.git

qla4xxx: Initialize hardware queue for ISP40XX

Issue:
System crash while target discovery for ISP40XX

Root cause:
Function qla4xxx_init_rings() is not called for ISP40XX

Fix:
Call function qla4xxx_init_rings() for ISP40XX from
qla4xxx_start_firmware().
