usb: Use fallthrough pseudo-keyword

2020-07-10T06:55:17+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.

USB: atm: Use the correct style for SPDX License Identifier

2020-03-17T19:03:28+00:00

This patch corrects the SPDX License Identifier style in header file related to USB DSL modem support drivers. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used).

USB: Replace zero-length array with flexible-array member

2020-02-23T18:24:51+00:00

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

USB: atm: ueagle-atm: add missing endpoint check

2019-12-10T12:11:22+00:00

Make sure that the interrupt interface has an endpoint before trying to access its endpoint descriptors to avoid dereferencing a NULL pointer. The driver binds to the interrupt interface with interface number 0, but must not assume that this interface or its current alternate setting are the first entries in the corresponding configuration arrays.

treewide: Use sizeof_field() macro

USB: atm: cxacru: convert to use dev_groups

2019-08-09T05:55:45+00:00

USB drivers now support the ability for the driver core to handle the creation and removal of device-specific sysfs files in a race-free manner. Take advantage of that by converting the driver to use this by moving the sysfs attributes into a group and assigning the dev_groups pointer to it.
