Subject: [PATCH] wifi: ath10k: fix PCI and SNOC RX pipe operations
Date: Thu, 13 Jul 2023 19:00:57 +0300 [thread overview]
Message-ID: <20230713160101.333483-1-dmantipov@yandex.ru> (raw)
Since 'mod_timer()' expects expiration time in jiffies, add
missing 'msecs_to_jiffies()' in 'ath10k_pci_rx_post_pipe()'
and 'ath10k_snoc_rx_post_pipe()'. Also simplify the loops
and fix number of loop iterations in the former (it should
be equal to 'num' (i.e. number of buffers) and not 'num + 1'.
Fixes: 728f95eef523 ("ath10k: rework posting pci rx buffers")
Fixes: a6e149a9ff03 ("ath10k: add hif start/stop methods for wcn3990 snoc layer")
