Subject: [SCSI] bsg: copy the cmd_type field to the subordinate request for bidi
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=40f620286dd08e29c995ca631f45e8d03f4fe1be;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[SCSI] bsg: copy the cmd_type field to the subordinate request for bidi

This fixes a problem in SCSI where we use the (previously
uninitialised) cmd_type via blk_pc_request() to set up the transfer in
scsi_init_sgtable().
