51f3a47889 scsi: core: Introduce the scsi_cmd_to_rq() function 
The 'request' member of struct scsi_cmnd is superfluous. The struct request
and struct scsi_cmnd data structures are adjacent and hence the request
pointer can be derived easily from a scsi_cmnd pointer. Introduce a helper
function that performs that conversion in a type-safe way. This patch is
the first step towards removing the request member from struct
scsi_cmnd. Making that change has the following advantages:

 - This is a performance optimization since adding an offset to a pointer
   takes less time than dereferencing a pointer.

 - struct scsi_cmnd becomes smaller.

10163cee1f scsi: ufs: ufshpb: Do not report victim error in HCM 
In host control mode, eviction is perceived as an extreme measure. There
are several conditions that both the entering and exiting regions should
meet, so that eviction will take place.

The common case however, is that those conditions are rarely met, so it is
normal that the act of eviction fails.  Therefore, do not report an error
in host control mode if eviction fails.

07106f86ae scsi: ufs: ufshpb: Use a correct max multi chunk 
In HPB2.0, if pre_req_min_tr_len < transfer_len < pre_req_max_tr_len, the
driver is expected to send a HPB-WRITE-BUFFER companion to HPB-READ.

The upper bound should fit into a single byte, regardless of bMAX_
DATA_SIZE_FOR_HPB_SINGLE_CMD which being an attribute (u32) can be
significantly larger.

To further illustrate the issue, consider the following scenario:

 - SCSI_DEFAULT_MAX_SECTORS is 1024 limiting the I/O chunks to 512KB

 - The OEM changes scsi_host_template .max_sectors to be 2048 which allows
   for 1MB requests: transfer_len = 256

 - pre_req_max_tr_len = HPB_MULTI_CHUNK_HIGH = 256

 - ufshpb_is_supported_chunk() returns true (256 <= 256)

 - WARN_ON_ONCE(256 > 256) doesn't warn

 - ufshpb_set_hpb_read_to_upiu() casts transfer_len to u8: transfer_len = 0

 - The command is failing with ILLEGAL REQUEST
