Merge tag 'qcom-drivers-for-6.11-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
A few more Qualcomm driver updates for v6.11
This adds a quirk to skip using the newly introduced SHM Bridge
implementation while regressions are being investigated.
One occurance of return no_free_ptr() is replaced with return_ptr() to
make code easier to read. llcc, mdt_loader, ocmem, pdr, socinfo and
wcnss drivers gets simplified using cleanup.h.
* tag 'qcom-drivers-for-6.11-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux:
firmware: qcom: tzmem: blacklist more platforms for SHM Bridge
soc: qcom: wcnss: simplify with cleanup.h
soc: qcom: pdr: simplify with cleanup.h
soc: qcom: ocmem: simplify with cleanup.h
soc: qcom: mdt_loader: simplify with cleanup.h
soc: qcom: llcc: simplify with cleanup.h
firmware: qcom: tzmem: simplify returning pointer without cleanup
soc: qcom: socinfo: Add PM6350 PMIC
