Changelog: v4 - v5: 1. Rebased patch 2. In the patch 3/5, change "param_size > buff_len" to "(param_offset + param_size) > buff_len" v3 - v4: 1. add desc_id >= QUERY_DESC_IDN_MAX check in patch 4/5 (Avri Altman) 2. update buff_len to hold the true descriptor size in 4/5 (Avri Altman) 3. add new patch 3/5 v2 - v3: 1. Fix typo in the commit message (Avri Altman & Bart van Assche) 2. Delete ufshcd_init_desc_sizes() in patch 3/4 (Stanley Chu) 3. Remove max_t() and buff_len in patch 1/4 (Bart van Assche) 4. Add patch 4/4 to compatable with 3.1 UFS unit descriptor length v1 - v2: 1. split patch 2. fix one compiling WARNING (Reported-by: kbuild test robot <lkp@intel.com>) Bart van Assche (1): scsi: ufs: remove max_t in ufs_get_device_desc Bean Huo (4): scsi: ufs: delete ufshcd_read_desc() scsi: ufs: fix potential access NULL pointer while memcpy scsi: ufs: cleanup ufs initialization path scsi: ufs: add compatibility with 3.1 UFS unit descriptor length drivers/scsi/ufs/ufs.h | 11 +- drivers/scsi/ufs/ufs_bsg.c | 5 +- drivers/scsi/ufs/ufshcd.c | 207 +++++++++---------------------------- drivers/scsi/ufs/ufshcd.h | 16 +-- 4 files changed, 54 insertions(+), 185 deletions(-)
