Subject: null_blk: use available 'dev' in nullb_device_power_store()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b3c3051220f3e2a576ba8008c4a87b7d4c8a35e8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

null_blk: use available 'dev' in nullb_device_power_store()

We already have this pointer, no need to use to_nullb_device()
again.
