commit 57f31326518e98ee4cabf9a04efe00ed57c54147 upstream. The reselection interrupt gets disabled during selection and must be re-enabled when hostdata->connected becomes NULL. If it isn't re-enabled a disconnected command may time-out or the target may wedge the bus while trying to reselect the host. This can happen after a command is aborted. Fix this by enabling the reselection interrupt in NCR5380_main() after calls to NCR5380_select() and NCR5380_information_transfer() return.

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.
