treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Input: gtco - fix extra-descriptor debug message

2020-01-10T22:42:58+00:00

Make sure to use the current altsetting when printing size of any extra
descriptors of the interface.

Also fix the s/endpoint/interface/ mixup in the message itself.

Input: gtco - fix endpoint sanity check

2020-01-10T22:42:57+00:00

The driver was checking the number of endpoints of the first alternate
setting instead of the current one, something which could lead to the
driver binding to an invalid interface.

This in turn could cause the driver to misbehave or trigger a WARN() in
usb_submit_urb() that kernels with panic_on_warn set would choke on.

Input: aiptek - use descriptors of current altsetting

2020-01-10T22:42:56+00:00

Make sure to always use the descriptors of the current alternate setting
to avoid future issues when accessing fields that may differ between
settings.

The driver was checking the number of endpoints of the first alternate
setting instead of the current one, something which could be used by a
malicious device (or USB descriptor fuzzer) to trigger a NULL-pointer
dereference.
