Subject: block/nullb: delete unnecessary memory free
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=060fd198a3e113047da456f15889579067e6b75f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

block/nullb: delete unnecessary memory free

Commit 2984c86(nullb: factor disk parameters) has a typo. The
nullb_device allocation/free is done outside of null_add_dev. The commit
accidentally frees the nullb_device in error code path.
