* iwmc3200wifi: cleanup unneeded debugfs error handlingJohn W. Linville2010-05-03
| | | | | | | | | | | | | | "iwl: cleanup: remove unneeded error handling" missed the one in if_sdio_debugfs_init(). I don't think we even need to check -ENODEV ourselves because if DEBUG_FS is not compiled in, all the debugfs utility functions will become no-op.

* iwl: cleanup: remove unneeded error handlingDan Carpenter2010-04-28
| | | | | | | | | | | | | | | | | | | | | | This is just a cleanup and doesn't change how the code works. debugfs_create_dir() and debugfs_create_file() return an error pointer (-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs they return NULL. This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W.

* rt2x00: rt2800lib: update rfcsr & bbp init code for SoC devicesHelmut Schaa2010-04-28
| | | | | | | | | | | | | | | | | | Update the rfcsr and bbp init code for SoC devices to match with the latest Ralink driver. To have better control over which values are used for the register initialization create a new function rt2800_is_305x_soc which checks for SoC interface type, the correct RT chipset and the correct RF chipset. This is based on the assumption that all rt305x SoC devices use a rt2872 and rf3020/rf3021/rf3022. In case an unknown RF chipset is found on a SoC device with a rt2872 don't treat it as rt305x and just print a message.

* wl1271: Rewrite hardware keep-alive handlingJuuso Oikarinen2010-04-28
| | | | | | | | | | | | | | | | The driver had a join command without keep-alive restart procedures in the channel changing code. After associated scans, the mac80211 does re-set the current channel, causing the join to occur. This would stop the hardware keep alive. To make the joins safer in this respect, this patch adds a join function that does the hardware-keep-alive magic along the join. This is now invoked in the above mentioned scenario, and also other scenarios.

* wl1271: Improve command pollingJuuso Oikarinen2010-04-28
| | | | | | | | | | | | | | | | In testing I noticed that the wl1271 commands fall into two categories. In the first category are "fast" commands, these mostly take only 0 or 1 polls to complete, but occasionally upto 50 (giving a 0.5ms execution time.) In the second category, the command completion takes well more than 0.5ms (from 1.5ms upwards.) This patch fixes command polling such that it is optimal for the fast commands, but also allows sleep for the longer ones.

* ath9k: Avoid corrupt frames being forwarded to mac80211.Vivek Natarajan2010-04-27
| | | | | | | | | | | | | | | If bit 29 is set, MAC H/W can attempt to decrypt the received aggregate with WEP or TKIP, eventhough the received frame may be a CRC failed corrupted frame. If this bit is set, H/W obeys key type in keycache. If it is not set and if the key type in keycache is neither open nor AES, H/W forces key type to be open. But bit 29 should be set to 1 for AsyncFIFO feature to encrypt/decrypt the aggregate with WEP or TKIP.

* ath9k_hw: Fix TX interrupt mitigation settingsLuis R. Rodriguez2010-04-27
| | | | | | | | | | | | | | | TX interrupt mitigation reduces the number of interrupts by addressing several interrupt actions (AR_IMR_TXOK, AR_IMR_TXDESC) all in one interrupt so when enabling it discard setting the other interrupts.
