Subject: iscsi-target: fix invalid flags in text response
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=310d40a973c560a24c79f84cb5f16dc540a05686;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

iscsi-target: fix invalid flags in text response

In case of multiple text responses iscsi-target
sets both 'F' and 'C' bit for the final text response
pdu, this issue happens because hdr->flags is not
zeroed out before ORing with 'F' bit.

This patch removes the | operator to fix this issue.
