[ Upstream commit756a7f9087] While initializing spectral, the magic value is getting written to the invalid memory address leading to random boot-up crash. This occurs due to the incorrect index increment in ath11k_dbring_fill_magic_value function. Fix it by replacing the existing logic with memset32 to ensure there is no invalid memory access. Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01838-QCAHKSWPL_SILICONZ-1 Fixes:d3d358efc5("ath11k: add spectral/CFR buffer validation support") Signed-off-by: P Praneesh <quic_ppranees@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20230321052900.16895-1-quic_ppranees@quicinc.com Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
