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

usb: chipidea: fix static checker warning for NULL pointer

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

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

Hi Greg,

This patch does not need to go stable tree, this issue is introduced by v5.0-rc1. Thanks.

Peter

During the static checker, "data->usbmisc_data" may be NULL. Fix it by adding this pointer judgement before using.
