Subject: [SCSI] aha152x: use bounce buffer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b1ee0795276f976118f832313488e6daf83ff542;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[SCSI] aha152x: use bounce buffer

Cause highmem buffers to be bounced to low memory until this
driver supports highmem addresses.  Otherwise it just oopses
on NULL buffer addresses.
