Please drop the table_count member from the smu_table structure as it's totally unused.
With that fixed, the patch is reviewed-by: Evan Quan <evan.quan@xxxxxxx>

> Subject: [PATCH] drm/amd/powerplay: replace smu->table_count with
> SMU_TABLE_COUNT in smu
>
> fix bellow patch issue:
> drm/amd/powerplay: introduce smu table id type to handle the smu table
> for each asic
> ----
> "This patch introduces new smu table type, it's to handle the different smu
> table defines for each asic with the same smu ip."
>
> before:
> use smu->table_count to represent the actual table count in smc firmware
> use actual table count to check smu function parameter about smu table
> after:
> use logic table count "SMU_TABLE_COUNT" to check function parameter
> because table id already mapped in smu driver, and smu function will use
> logic table id not actual table id to check func parameter.
