[PATCH v2 00/29] UFS patches for kernel v5.19

[Bart Van Assche <bvanassche@acm.org>]

Hi Martin,

This patch series includes the following changes:
- Separation of UFS core and UFS driver source code into separate directories.
- Split the ufshcd.h header file into two header files - one file that
  defines the interface with UFS drivers and another file with definitions
  only used in the core.
- Multiple source code cleanup patches.
- A few patches with minor functional changes.

Please consider these changes for kernel v5.19.

Thank you,

Bart.

Changes compared to v1:
* Added a new patch with a source code comment spelling fix.
* Included a HPB change in patch "Simplify statements that return a boolean".
* Removed a superfluous test from patch "Remove ufshcd_lrb.sense_buffer".
* Dropped patch "Remove the LUN quiescing code from ufshcd_wl_shutdown()".
* Fixed indentation in patch "Make the config_scaling_param calls type safe".
* Improved the description of patch "Remove locking from around single register
  writes".
* Modified patch "Minimize #include directives" such that the current order of
  #include directives is preserved.
* Fixed support for CONFIG_SCSI_UFS_HWMON=n in patch "Split the ufshcd.h header
  file".
* In patch "Split the drivers/scsi/ufs directory", moved the UFS source files
  from drivers/scsi/ufs/ into drivers/ufs/.
