This is a note to let you know that I've just added the patch titled

bus: mhi: pci-generic: Add missing

to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-testing branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open.

If you have any questions about this process, please let me know.

From: Christophe JAILLET christophe.jaillet@wanadoo.fr Date: Mon, 21 Jun 2021 21:46:13 +0530 Subject: bus: mhi: pci-generic: Add missing 'pci_disable_pcie_error_reporting()' calls

If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it must be undone by a corresponding 'pci_disable_pcie_error_reporting()' call

Add the missing call in the error handling path of the probe and in the remove function.
