media: platform: mtk-mdp3: fix uninitialized variable in mdp_path_config()
Fix the build warnings that were detected by the linux-media
build scripts tool:
drivers/media/platform/mediatek/mdp3/mtk-mdp3-cmdq.c:
In function 'mdp_path_config.isra':
drivers/media/platform/mediatek/mdp3/mtk-mdp3-cmdq.c:
warning: 'ctx' may be used uninitialized [-Wmaybe-uninitialized]
| out = CFG_COMP(MT8195, ctx->param, outputs[0]);
| ~~~^~~~~~~
drivers/media/platform/mediatek/mdp3/mtk-img-ipi.h: note:
in definition of macro 'CFG_COMP'
| (IS_ERR_OR_NULL(comp) ? 0 : _CFG_COMP(plat, comp, mem))
| ^~~~
drivers/media/platform/mediatek/mdp3/mtk-mdp3-cmdq.c:
note: 'ctx' was declared here
| struct mdp_comp_ctx *ctx;
