Subject: [SCSI] mptsas: don't complain on bogus slave_alloc calls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=23f236ed2748fca0bcba304f4f9e3eacda51e91c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] mptsas: don't complain on bogus slave_alloc calls

When people use the userspace scanning facilities on SAS hardware the
LLDD gets bogus slave_alloc calls.  Just fail those gracefully instead
of printing a warning in mptsas and another one in the midlayer.
