This patch fixes the command length alignment issue for Intel Bluetooth 8260. The length of parameters in the firmware downloading command must be multiplication of 4. If not, the command must append Intel_NOP command with extra parameters, zeros, at the end, and the firmware file is already included Intel_NOP command for alignment. This patch checks the next command and if the next command is Intel_NOP command, it reads the Intel_NOP command and send them together. For example, if the data from the firmware file looks like this: 8E FC 03 11 22 33 02 FC 03 00 00 00 Previously, btusb sends two commands: 09 FC 06 8E FC 03 11 22 33 09 FC 06 02 FC 03 00 00 00 This won't work because the length of parameters are 6 which violates the 4 byte alignment. This patch will append them together and send as one command: 09 FC 0C 8E FC 03 11 22 33 02 FC 03 00 00 00 Based on previous work from Tedd Ho-Jeong An <tedd.an@intel.com> Reported-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Tested-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Cc: stable@vger.kernel.org |
