treewide: Replace more open-coded allocation size multiplications

2018-10-06T01:06:30Z

As done treewide earlier, this catches several more open-coded allocation size calculations that were added to the kernel during the merge window. This performs the following mechanical transformations using Coccinelle: kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...) kvzalloc(a * b, ...) -> kvcalloc(a, b, ...) devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

Bluetooth: hci_ldisc: Free rw_semaphore on close

2018-09-11T11:33:57Z

The percpu_rw_semaphore is not currently freed, and this leads to a crash when the stale rcu callback is invoked. DEBUG_OBJECTS detects this.

Bluetooth: Make BT_HCIUART_RTL configuration option depend on ACPI

2018-08-21T14:36:12Z

At the moment we only support ACPI enumeration for serial port attached RTL bluetooth controllers. This commit adds a dependency on ACPI to the BT_HCIUART_RTL configuration option, fixing the following warning when ACPI is not enabled: drivers/bluetooth/hci_h5.c:920:22: warning: 'rtl_vnd' defined but not used Cc: Arnd Bergmann Reported-by: Arnd Bergmann Signed-off-by: Hans de Goede Acked-by: Arnd Bergmann Acked-by: Geert Uytterhoeven Signed-off-by: Marcel Holtmann

Bluetooth: mediatek: pass correct size to h4_recv_buf()

2018-08-13T13:59:39Z

We're supposed to pass the number of elements in the mtk_recv_pkts, not the number of bytes. Fixes: 7237c4c9ec92 ("Bluetooth: mediatek: Add protocol support for MediaTek serial devices") Signed-off-by: Dan Carpenter Signed-off-by: Marcel Holtmann

Bluetooth: Introduce BT_HCIUART_RTL configuration option

Bluetooth: mediatek: Add protocol support for MediaTek serial devices

2018-08-07T19:33:25Z

This adds a driver based on serdev driver for the MediaTek serial protocol based on running H:4, which can enable the built-in Bluetooth device inside MT7622 SoC. Signed-off-by: Sean Wang Signed-off-by: Marcel Holtmann

Bluetooth: btqca: Introduce HCI_EV_VENDOR and use it

2018-08-06T18:25:05Z

Using HCI_VENDOR_PKT for vendor specific events does work since it has also the value 0xff, but it is actually the packet type indicator constant and not the event constant. So introduce HCI_EV_VENDOR and use it. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: h5: Fix missing dependency on BT_HCIUART_SERDEV

2018-08-04T21:23:32Z

This driver was recently updated to use serdev, so add the appropriate dependency. Without this one can get compiler warnings like this if CONFIG_SERIAL_DEV_BUS is not enabled: CC [M] drivers/bluetooth/hci_h5.o drivers/bluetooth/hci_h5.c:934:36: warning: ‘h5_serdev_driver’ defined but not used [-Wunused-variable] static struct serdev_device_driver h5_serdev_driver = { ^~~~~~~~~~~~~~~~ Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann
