Subject: HID: cp2112: add HIDRAW dependency
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=740ef39bce15d7d74a5b02b7b0e6abb472a9c76c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

HID: cp2112: add HIDRAW dependency

commit cde3076bdc38bf436e517a379759a9092c6ffd4f upstream.

Otherwise, with HIDRAW=n, the probe function crashes because of null
dereference of hdev->hidraw.

Fixes: 42cb6b35b9e6 ("HID: cp2112: use proper hidraw name with minor number")
