patch "staging: mt7621-pinctrl: fix uninitialized variable ngroups" added to staging-linus

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

staging: mt7621-pinctrl: fix uninitialized variable ngroups

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus 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 hopefully also be merged in Linus's tree for the next -rc kernel release.

Subject: staging: mt7621-pinctrl: fix uninitialized variable ngroups

Currently the for_each_node_with_property loop us incrementing variable ngroups however it was not initialized and hence will contain garbage. Fix this by initializing ngroups to zero.

Detected with static analysis with cppcheck:

drivers/staging/mt7621-pinctrl/pinctrl-rt2880.c:89]: (error) Uninitialized
variable: ngroups
