Subject: [PATCH AUTOSEL 6.14 01/54] wifi: ath9k: use unsigned long for activity check timestamp

From: Dmitry Antipov <dmantipov@...dex.ru>

[ Upstream commit 8fe64b0fedcb7348080529c46c71ae23f60c9d3e ]

Since 'rx_active_check_time' of 'struct ath_softc' is in jiffies,
prefer 'unsigned long' over 'u32' to avoid possible truncation in
'ath_hw_rx_inactive_check()'. Found with clang's -Wshorten-64-to-32,
compile tested only.
