======== - Use pci_try_reset_function() to reset the MHI function during recovery process to avoid the deadlock reported on the X1E80100 CRD device. The deadlock can happen if the caller has already acquired the 'device_lock()' while calling the recovery function. So using pci_try_reset_function() avoids the deadlock by returning -EAGAIN if the lock was already acquired. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEZ6VDKoFIy9ikWCeXVZ8R5v6RzvUFAme2ypUACgkQVZ8R5v6R zvWuKgf/eyQqHdgKU/v+FBF4g65bWj+EXYxwu8jhLxAsE1rlrwQSozHp7xb+RyNV P92DGkfX+Dplm4hAUnZKhqzoGtKAdeuyjcvs5/+1O2lWMojxkQlT3EUEc7YRNmVI aqFO+KaeqklF5HL8HOqkyFmiCoig9M63o4JWkjxyqTMFr2G3C671SAY5BSRVg6ms 9gV8j+8sI+DkElsSSd6/n3jibEplHx34g15HCstGoU5/rAke3Gl97l3mK7shbRC0 FORoTSH/L7CguLDJzQmi2nq9tQNflIR4YNaEHWhYbaSziDVYuQ+XB+mIZ7lGn/UD 3EqvKsJw5KS+7TvdhuiCi1k0V+26rA== =DoWM -----END PGP SIGNATURE----- Merge tag 'mhi-fixes-for-v6.14' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mani/mhi into char-misc-linus Manivannan writes: MHI Host ======== - Use pci_try_reset_function() to reset the MHI function during recovery process to avoid the deadlock reported on the X1E80100 CRD device.

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 reStructuredText 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.
