Subject: scsi: mvsas: replace kfree with scsi_host_put
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf99dc30bcc56c33243b5bbfef9d8ea943dd2e1c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scsi: mvsas: replace kfree with scsi_host_put

The return value of scsi_host_alloc() should be released by
scsi_host_put(). However, in function mvs_pci_init(), kfree()
is used. This patch replaces kfree() with scsi_host_put() to avoid
possible memory leaks.
