Subject[ 22/68] ath9k_hw: avoid possible infinite loop in ar9003_get_pll_sqsum_dvc
Date
From: Greg KH <gregkh@linuxfoundation.org>

3.0-stable review patch. If anyone has any objections, please let me know.

------------------
From: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com>

commit f18e3c6b67f448ec47b3a5b242789bd3d5644879 upstream.

"ath9k: Fix softlockup in AR9485" with commit id
64bc1239c790e051ff677e023435d770d2ffa174 fixed the reported
issue, yet its better to avoid the possible infinite loop
in ar9003_get_pll_sqsum_dvc by having a timeout as suggested
by ath9k maintainers.

Based on my testing PLL's locking measurement is done in
~200us (2 iterations).
