soc: qcom: cmd-db: Use devm_memremap() to fix memory leak in cmd_db_dev_probe

2026-02-26T23:00:52+00:00

[ Upstream commit 0da7824734d8d83e6a844dd0207f071cb0c50cf4 ] If cmd_db_magic_matches() fails after memremap() succeeds, the function returns -EINVAL without unmapping the memory region, causing a potential resource leak. Switch to devm_memremap to automatically manage the map resource.

soc: qcom: smem: fix qcom_smem_is_available and check if __smem is valid

2026-01-28T15:10:53+00:00

Commit 7a94d5f31b54 ("soc: qcom: smem: better track SMEM uninitialized state") changed the usage of __smem and init now as an error pointer instead of NULL. qcom_smem_is_available() wasn't updated to reflect this change and also .qcom_smem_remove doesn't reset it on module exit. Update both entry to reflect new handling of __smem.

soc: qcom: mdt_loader: rename 'firmware' parameter of qcom_mdt_load()

2025-11-11T15:48:57+00:00

In the 'mdt_loader.h' header, both the prototype and the inline version of the qcom_mdt_load() function uses 'fw_name' as name for the firmware name parameter. Additionally, the other qcom_mdt_* functions are using that as well. For consistency, rename the 'firmware' parameter in the implementation of the qcom_mdt_load() to 'fw_name' and update the function accordingly. No functional changes.

soc: qcom: mdt_loader: merge __qcom_mdt_load() and qcom_mdt_load_no_init()

2025-11-11T15:48:56+00:00

The qcom_mdt_load_no_init() function is just a simple wrapper around of __qcom_mdt_load(). Since commit 0daf35da397b ("soc: qcom: mdt_loader: Remove pas id parameter") both functions are using the same type of parameters and providing the same functionality. Keeping two functions for the same purpose is superfluous, so rename the __qcom_mdt_load() function to qcom_mdt_load_no_init() and remove the wrapper. No functional changes.

Add support for socinfo version 20. Version 20 adds a new field package id and its zeroth bit contain information that can be can be used to tune temperature thresholds on devices which might be able to withstand higher temperatures. Zeroth bit value 1 means that its heat dissipation is better and more relaxed thermal scheme can be put in place and 0 means a more aggressive scheme may be needed.
