wifi: ath12k: fix incorrect logic of calculating vdev_stats_id

Browse source

[ Upstream commit 019b58dcb6 ]

During calculate vdev_stats_id, will compare vdev_stats_id with
ATH12K_INVAL_VDEV_STATS_ID by '<='. If vdev_stats_id is relatively
small, then assign ATH12K_INVAL_VDEV_STATS_ID to vdev_stats_id.

This logic is incorrect. Firstly, should use '>=' instead of '<=' to
check if this u8 variable exceeds the max valid range.

Secondly, should use the maximum value as comparison value.

Correct comparison symbols and use the maximum value
ATH12K_MAX_VDEV_STATS_ID for comparison.
