Subject: rbd: drop needless test in rbd_rq_fn()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=38f5f65e9d25b0a7270c337a35c724ca3d56f4d8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rbd: drop needless test in rbd_rq_fn()

There's a test for null rq pointer inside the while loop in
rbd_rq_fn() that's not needed.  That same test already occurred
in the immediatly preceding loop condition test.
