Merge patch series "Multiple cleanup patches for the UFS driver"
Bart Van Assche <bvanassche@acm.org> says:
Hi Martin,
This patch includes the following changes, none of which should change the
functionality of the UFS host controller driver:
- Improve the kernel-doc headers further.
- Fix multiple W=2 compiler warnings.
- Simplify ufshcd_abort_all().
- Simplify the code for creating and parsing UFS Transport Protocol (UTP)
headers.
Please consider this patch series for the next merge window.
Thanks,
Bart.

Quirk UFSHCD_QUIRK_MCQ_BROKEN_INTR is introduced for hosts that implement a
different interrupt topology from the UFSHCI 4.0 spec. Some hosts raise
per hw queue interrupt in addition to CQES (traditional) when ESI is
disabled.
Enabling this quirk will disable CQES and use only per hw queue interrupt.
