Subject: xen-scsifront: Add a missing call to kfree
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1eb08545c0a3a2249ad53e393383cc06163d0d16;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

xen-scsifront: Add a missing call to kfree

Most error branches following the call to kmalloc contain
a call to kfree. This patch add these calls where they are
missing.

This issue was found with Hector.
