In the Linux kernel, the following vulnerability has been resolved:
usb: chipidea: ci_hdrc_imx: fix usbmisc handling
usbmisc is an optional device property so it is totally valid for the corresponding data->usbmisc_data to have a NULL value.
Check that before dereferencing the pointer.
Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool.
