USB: serial: cp210x: fix CP2105 GPIO registration 2021-12-14T08:22:05+00:00 Johan Hovold johan@kernel.org 2021-11-26T09:43:48+00:00 83b67041f3eaf33f98a075249aa7f4c7617c2f85 When generalising GPIO support and adding support for CP2102N, the GPIO registration for some CP2105 devices accidentally broke. Specifically, when all the pins of a port are in "modem" mode, and thus unavailable for GPIO use, the GPIO chip would now be registered without having initialised the number of GPIO lines. This would in turn be rejected by gpiolib and some errors messages would be printed (but importantly probe would still succeed). Fix this by initialising the number of GPIO lines before registering the GPIO chip. Note that as for the other device types, and as when all CP2105 pins are muxed for LED function, the GPIO chip is registered also when no pins are available for GPIO use.

USB-serial updates for 5.16-rc1

Here are the USB-serial updates for 5.16-rc1, including:

 - conversions of usb_control_msg() calls to use the new wrappers where
   appropriate
 - fix of the keyspan probe error handling after a low-order allocation
   failure (e.g. due to fault injection)
 - allow hung up ports to be runtime suspended

Included are also some related clean ups.

If keyspan_port_probe() fails to allocate memory for an out_buffer[i] or
in_buffer[i], the previously allocated memory for out_buffer or
in_buffer needs to be freed on the error handling path, otherwise a
memory leak will result.
