Subject: [PATCH v5 0/4] ufs: core: Always read the descriptors with max length
Date: Sun, 11 Dec 2022 15:05:07 +0200 [thread overview]
Message-ID: <1670763911-8695-1-git-send-email-Arthur.Simchaev@wdc.com> (raw)
v4--v5:
Change patch 2 according to Bart's comment
v3--v4:
Add "Reviewed-by" to patch's commits
Use kzalloc instead of kmalloc in drivers/ufs/core/ufshcd.c - patch 2/4
v2--v3:
Based on Bean's comments:
1)Use kzalloc instead of kmalloc in ufshcd_set_active_icc_lvl - patch 2/4
2)Delete UFS_RPMB_UNIT definition - patch 2/4
3)Delete len description - patch 3/4
v1--v2:
Fix argument warning in ufshpb.c
Read any descriptor with a maximum size of QUERY_DESC_MAX_SIZE.
According to the spec the device rerurns the actual size.
Thus can improve code readability and save CPU cycles.
While at it, cleanup few leftovers around the descriptor size parameter.
