soc: mediatek: svs: Fix memory leak in svs_enable_debug_write()

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

[ Upstream commit 6259094ee806fb813ca95894c65fb80e2ec98bf1 ] In svs_enable_debug_write(), the buf allocated by memdup_user_nul() is leaked if kstrtoint() fails. Fix this by using __free(kfree) to automatically free buf, eliminating the need for explicit kfree() calls and preventing leaks.

soc: mediatek: mtk-mutex: Fix confusing usage of MUTEX_MOD2

2025-06-25T13:59:00+00:00

The usage of MUTEX_MOD1 and MUTEX_MOD2 for calculating mod settings over 32 has been confusing. To improve consistency and clarity, these defines need to fit into the same MUTEX_MOD define as possible. However, MUTEX_MOD1 cannot be directly used for all SoCs because, for example, the mod1 register (0x34) of MT2712 is not adjacent to its mod0 register (0x2c). To address this, a `mutex_mod1_reg` field is introduced in the mutex driver data structure. This allows all SoCs to use a unified MUTEX_MOD to determine their register offsets. With this change, the separate usage of MUTEX_MOD1 and MUTEX_MOD2 is eliminated, simplifying the logic for obtaining offsets and mod IDs.

Rename the MT8183 and MT8195 bandwidth constraints data structure to, respectively, dvfsrc_bw_constr_v1 and dvfsrc_bw_constr_v2, as the actual constraints are depending on the DVFSRC version rather than on the SoC. While at it, to prepare for adding a new SoC, also move the two structures at the start of the platform data code section.
