2013-08-16iwlwifi: use a macro for default probe lengthLuciano Coelho
Instead of assigning the default max probe length to 200 in the main code, create a macro for consistency and clarity. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-08-16iwlwifi: mvm: refactor resume from WoWLAN codeJohannes Berg
To be able to add more logic to the resume code, refactor it a bit, moving some status checking/reporting logic into a new function. The locking becomes a bit odd (one of the new functions now unlocks the mutex) but this will be required to call new mac80211 APIs in there later.

2013-08-12iwlwifi: mvm: don't clear tbl->win mistakenlyEliad Peller

2013-08-12iwlwifi: pcie: returning positive instead of negativeDan Carpenter
There is a missing '-' character here so we return positive 'ENOMEM' instead of negative. The caller doesn't care. All non-zero returns are translated to '-ENOMEM' in iwl_pcie_nic_init().

2013-08-12iwlwifi: pcie: don't swallow error codes in iwl_trans_pcie_alloc()Luciano Coelho
The iwl_trans_pcie_alloc() function doesn't pass up error codes returned from functions it calls, swallowing them and returning NULL in all failure cases. The caller checks if the return value is NULL and returns -ENOMEM. This is not correct, because in certain cases the failure was not due to an OOM situation. To fix this, modify the iwl_trans_pcie_alloc() function to use ERR_PTR() to return error codes and clean up the error handling code a bit.

2013-07-31iwlwifi: mvm: fix debugfs restart if fw_restart is disabledEran Harary
If fw_restart is disabled, using the fw_restart debugfs file will enable fw_restart and then send the failing command, but this still frequently fails restart because it resets fw_restart afterwards and is thus racy.

If we get a firmware error during restart, we currently abandon any hope and simply fail, getting stuck until the driver is reloaded. Unfortunately, there isn't really much else we can do since restart will likely continue to fail, and asking mac80211 for disconnection just causes more error.
