[SRU][O][PATCH 0/1] Poor bluetooth performance on Lenovo X13s (LP: #2089357)

[Juerg Haefliger]

BugLink: https://bugs.launchpad.net/bugs/2089357

[ Impact ]

Currently, the built-in NVM is loaded because Qualcomm hasn't released correct
 NVM files until recently. This results in poor bluetooth performance.

Firmware finally landed in upstream linux-firmware:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=77a11ffc5a0aaaadc870793d02f6c6781ee9f598

Required kernel patch:
https://lore.kernel.org/all/20241116-x13s_wcn6855_fix-v2-1-c08c298d5fbf@quicinc.com/

[ Test Plan ]

Boot and check that the new firmware is loaded and that bluetooth connections can be established.
dmesg:
[ 6.159831] Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv

[ Where Problems Could Occur ]

Kernel patch specific to QCA bluetooth driver. New firmware that is only loaded
 on specific Qualcomm HW. Should not affect any other users.
