soc: qcom: smem: fix hwspinlock resource leak in probe error paths

2025-12-18T12:59:28+00:00

[ Upstream commit dc5db35073a19f6d3c30bea367b551c1a784ef8f ] The hwspinlock acquired via hwspin_lock_request_specific() is not released on several error paths. This results in resource leakage when probe fails. Switch to devm_hwspin_lock_request_specific() to automatically handle cleanup on probe failure. Remove the manual hwspin_lock_free() in qcom_smem_remove() as devm handles it automatically.

soc: qcom: gsbi: fix double disable caused by devm

2025-12-18T12:59:22+00:00

[ Upstream commit 2286e18e3937c69cc103308a8c1d4898d8a7b04f ] In the commit referenced by the Fixes tag, devm_clk_get_enabled() was introduced to replace devm_clk_get() and clk_prepare_enable(). While the clk_disable_unprepare() call in the error path was correctly removed, the one in the remove function was overlooked, leading to a double disable issue. Remove the redundant clk_disable_unprepare() call from gsbi_remove() to fix this issue. Since all resources are now managed by devres and will be automatically released, the remove function serves no purpose and can be deleted entirely.

net: ethernet: ti: netcp: Standardize knav_dma_open_channel to return NULL on error

2025-12-01T10:46:05+00:00

[ Upstream commit 90a88306eb874fe4bbdd860e6c9787f5bbc588b5 ] Make knav_dma_open_channel consistently return NULL on error instead of ERR_PTR. Currently the header include/linux/soc/ti/knav_dma.h returns NULL when the driver is disabled, but the driver implementation does not even return NULL or ERR_PTR on failure, causing inconsistency in the users. This results in a crash in netcp_free_navigator_resources as followed (trimmed): Unhandled fault: alignment exception (0x221) at 0xfffffff2 [fffffff2] *pgd=80000800207003, *pmd=82ffda003, *pte=00000000 Internal error: : 221 [#1] SMP ARM Modules linked in: CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.17.0-rc7 #1 NONE Hardware name: Keystone PC is at knav_dma_close_channel+0x30/0x19c LR is at netcp_free_navigator_resources+0x2c/0x28c [...

TRIM...] Standardize the error handling by making the function return NULL on all error conditions. The API is used in just the netcp_core.c so the impact is limited. Note, this change, in effect reverts commit 5b6cb43b4d62 ("net: ethernet: ti: netcp_core: return error while dma channel open issue"), but provides a less error prone implementation.

soc: ti: pruss: don't use %pK through printk

2025-11-13T20:36:46+00:00

[ Upstream commit a5039648f86424885aae37f03dc39bc9cb972ecb ] In the past %pK was preferable to %p as it would not leak raw pointer values into the kernel log. Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the regular %p has been improved to avoid this issue. Furthermore, restricted pointers ("%pK") were never meant to be used through printk(). They can still unintentionally leak raw pointers or acquire sleeping locks in atomic contexts. Switch to the regular pointer formatting which is safer and easier to reason about.
