* drivers: net: wireless: b43: Fix possible NULL ptr dereferenceFelipe Pena2013-10-181-1/+2
| | | | | | | | On the ternary expression the 'e' variable could be NULL dereferenced, when b43_nphy_get_rf_ctl_over_rev7 function returns NULL. Signed-off-by: Felipe Pena <felipensp@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | b43: N-PHY: use more bits for offset in RSSI calibrationRafał Miłecki2013-03-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When calculating "offset" for final RSSI calibration we're using numbers bigger than s8 can hold. We have for example: offset[j] = 232 - poll_results[j]; formula. If poll_results[j] is small enough (it usually is) we treat number's bit as a sign bit. For example 232 - 1 becomes: 0xE8 - 0x1 = 0xE7, which is not 231 but -25. This code was introduced in e0c9a0219a8f542e3946fe972a68aacf8c3f906c and caused stability regression on some cards, for ex. BCM4322. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | b43: N-PHY: increase initial value of "mind" in RSSI calibrationRafał Miłecki2013-03-271-2/+2
|/ | | | | | | | | | | | | | | We're using "mind" variable to find the VCM that got the best polling results. For each VCM we calculte "currd" which is compared to the "mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a value smaller than 40 makes no sense, so increase the initial value. This fixes a regression introduced in 3.4 by commit: e0c9a0219a8f542e3946fe972a68aacf8c3f906c (my BCM4322 performance dropped from 18,4Mb/s to 9,26Mb/s) Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: John W.
