[ Upstream commit 7f6ba4f12e6cbfdefbb95cfd8fc67ece6c15d799 ] As multiple requests are submitted to the ufs host controller in parallel there could be instances where the command completion interrupt arrives later for a request that is already processed earlier as the corresponding doorbell was cleared when handling the previous interrupt. Read the interrupt status in a loop after processing the received interrupt to catch such interrupts and handle it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
