scsi: ufs: core: Retry START_STOP on UNIT_ATTENTION
Commit 57d104c153d3 ("ufs: add UFS power management support") made the UFS driver submit a REQUEST SENSE command before submitting a power management command to a WLUN to clear the POWER ON unit attention. Instead of submitting a REQUEST SENSE command before submitting a power management command, retry the power management command until it succeeds. This is the preparation to get rid of all UNIT ATTENTION code which should be handled by users.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
