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

2020-02-28T07:30:02+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.

Bluetooth: btqca: Rename ROME specific variables to generic variables

2019-11-09T02:26:47+00:00

Variables which are named with rome are commonly used for all the
BT SoC's. Instead of continuing further, renamed them to generic
name.

Bluetooth: hci_qca: Send VS pre shutdown command.

2019-08-12T16:23:50+00:00

WCN399x chips are coex chips, it needs a VS pre shutdown
command while turning off the BT. So that chip can inform
BT is OFF to other active clients.

Bluetooth: hci_qca: Load customized NVM based on the device property

2019-07-06T10:55:39+00:00

QCA BTSOC NVM is a customized firmware file and different vendors may
want to have different BTSOC configuration (e.g. Configure SCO over PCM
or I2S, Setting Tx power, etc.) via this file. This patch will allow
vendors to download different NVM firmware file by reading a device
property "firmware-name".

Bluetooth: btqca: inject command complete event during fw download

2019-07-06T10:45:02+00:00

Latest qualcomm chips are not sending an command complete event for
every firmware packet sent to chip. They only respond with a vendor
specific event for the last firmware packet. This optimization will
decrease the BT ON time. Due to this we are seeing a timeout error
message logs on the console during firmware download. Now we are
injecting a command complete event once we receive an vendor specific
event for the last RAM firmware packet.
