soc: mediatek: mtk-svs: fix device leaks on mt8192 probe failure

2025-10-15T10:00:00+00:00

[ Upstream commit f1a68ba5739e42353609438e27a83b08d7f5cfd6 ] Make sure to drop the references taken by of_find_device_by_node() when looking up the thermal sensor and opp devices during probe on probe failure (e.g. probe deferral) and on driver unbind.

soc: mediatek: mtk-mutex: Reduce type size for mtk_mutex_data members

2024-07-30T08:58:46+00:00

All of mutex_mod and mutex_table_mod contain an array of bit numbers, which can go from 0 to 63, it is hence not needed to use an unsigned 32-bits integer to store that: change them to unsigned 8-bits instead. As for the mutex_sof table since this directly contains the values to write to the DISP_MUTEXn_CTL register, which has only bits [13:0] (so this register is effectively 14 bits long), change that to use unsigned 16-bits. The type of mutex_{mod,sof}_reg was also changed to 16 bits, as the maximum value that those will ever have is 0x800, because it calculates as 0x30 + (0x20 * n) where n's maximum value is 63. This reduces module size and brings no functional changes.
