Mediatek UFS reset function relies on Reset Control provided by reset-ti-syscon. To make Mediatek Reset Control work properly, select reset-ti-syscon to ensure it is being built. In addition, establish device_link to wait until reset-ti-syscon initialization is complete during UFS probing.

Hyper-V is observed to sometimes set multiple flags in the srb_status, such as ABORTED and ERROR. Current code in storvsc_handle_error() handles only a single flag being set, and does nothing when multiple flags are set. Fix this by changing the case statement into a series of "if" statements testing individual flags. The functionality for handling each flag is unchanged.

When an I/O error is reported by the underlying Hyper-V host, current code provides details only when the logging level is set to WARN, making it more difficult to diagnose problems in live customer situations. Fix this by reporting details at ERROR level, which is the default. Also add more information, including the Hyper-V error code, and the tag # so that the message can be matched with messages at the SCSI and blk-mq levels. Also, sense information logging is inconsistent and duplicative. The existence of sense info is first logged at WARN level, and then full sense info is logged at ERROR level. Fix this by removing the logging of the existence of sense info, and change the logging of full sense info to WARN level in favor of letting the generic SCSI layer handle such logging. With the change to WARN level, it's no longer necessary to filter out as noise any NOT READY sense info generated by the virtual DVD device.

As general cleanup and in preparation for subsequent patches: - Use min() instead of open coding. - Use set_host_byte() instead of open coding access to scsi_status field. - Collapse nested "if" statements to reduce indentation. - Fix other indentation. - Remove extra blank lines. No functional changes. [mkp: dropped status_byte() which no longer exists] Link: https://lore.kernel.org/r/1622827263-12516-1-git-send-email-mikelley@microsoft.comSigned-off-by:

Added RHBA and RPA attributes type and length. As per FC_GC_7 document section "Table 400 – Attribute Entry Types and associated Values" ASCII type attributes length can be vary from "4 to 256 byte". If we keep all RHBA ASCII attributes length 256 then total length is going upto 2750, which is far more than 2048 (max frame size). In libfc we do have logic to split FCP commands but not for CT commands. Practically all version/names get covered with in 64 bytes except OS name, for that we need 128 bytes. Hence length of all RBHA ASCII attributes is reduced to 64 bytes and 128 bytes in case of OS name. RPA attributes total length is within frame size.
