Bluetooth: bcm203x: remove superfluous header files

2022-03-18T16:12:09+00:00

bcm203x.c hasn't use any macro or function declared in linux/atomic.h. Thus, these files can be removed from bcm203x.c safely without affecting the compilation of the ./drivers/bluetooth module Signed-off-by: Mianhan Liu Signed-off-by: Marcel Holtmann

Bluetooth: Use fallthrough pseudo-keyword

2020-07-10T17:09:42+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.

Bluetooth: mark expected switch fall-throughs

2017-10-14T07:25:51+00:00

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. In this particular case, notice that I replaced the "deliberate fall-through..." comment with a "fall through" comment, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R.

USB: Disable hub-initiated LPM for comms devices.

2012-05-18T22:42:55+00:00

Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

USB: convert drivers/bluetooth/* to use module_usb_driver()

2011-11-18T17:47:34+00:00

This converts the drivers in drivers/bluetooth/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading. Cc: Marcel Holtmann Cc: "Gustavo F. Padovan" Signed-off-by: Greg Kroah-Hartman

Bluetooth: bcm203x: Use GFP_KERNEL in workqueue

2011-10-31T19:51:57+00:00

A workqueue is allowed to sleep so we can safely use GFP_KERNEL instead of GFP_ATOMIC. This is still legacy code when the driver used timer BHs and not a worqueue. Signed-off-by: David Herrmann Acked-by: Marcel Holtmann Signed-off-by: Gustavo F. Padovan
