Subject: qedr: ignore inline flag in read verbs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8b0cabc650a95a4f44de99aae6e8c128d70a40cd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

qedr: ignore inline flag in read verbs

In the current implementation a read verb with IB_SEND_INLINE may be
illegally configured.
In this fix we ignore the inline bit in the case of a read verb.
