RE: [PATCH] scsi: ufs-bsg: Remove ufs_bsg_get_query_desc_size function

Hi Bean. 

I think in any case we need remove the redundant  ufs_bsg_get_query_desc_size
function from ufs_bsg. As done in this patch and submit the another one in order to remove 
the desc size check in ufshcd.c entirely. 
Are you agree?  

Regards
Arthur
