* iwlagn: combine firmware code/dataJohannes Berg2011-04-22
| | | | | | | | | | | | | On new hardware, ucode images always come in pairs: code and data. Therefore, combine the variables into an appropriate struct and use that when both code and data are needed. Also, combine allocation and copying so that we have less code in total.

* iwlagn: implement synchronous firmware loadJohannes Berg2011-04-22
| | | | | | | | | | | | | | | | | The current firmware loading mechanism in iwlwifi is very hard to follow, and thus hard to maintain. To make it easier, make the firmware loading synchronous. For now, as a side effect, this removes a number of retry possibilities we had. It isn't typical for this to fail, but if it does happen we restart from scratch which this also makes easier to do should it be necessary.

* iwlagn: clean up & autodetect statisticsJohannes Berg2011-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no need to keep both normal and BT statistics versions around all the time in memory when we only use a subset of both. So keep only the subsets that we need in memory, depending on the debug config). Also, in doing so, we can remove all the calls to iwl_bt_statistics() in the driver as we'll just access the copied statistics now. Finally, also remove this call from the one place where it might still be needed and automatically detect what kind of statistics the device is sending based on their size. This way, we don't need to keep track of which devices do what any more, which is good since this is subject to change based on the ucode version (as some ucode even for non-BT devices will in fact use BT statistics). Warn upon encountering a statistics command from the ucode that isn't known, so we will find such issues earlier in the future.

* | net/wireless: use generic_file_llseek in debugfsArnd Bergmann2010-09-16
|/ | | | | | | | | | | | | | | | | | | | The default llseek operation is changing from default_llseek to no_llseek, so all code relying on the current behaviour needs to make that explicit. The wireless driver infrastructure and some of the drivers make use of generated debugfs files, so they cannot be converted by our script that automatically determines the right operation. All these files use debugfs and they typically rely on simple_read_from_buffer, so the best llseek operation here is generic_file_llseek. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: "John W.
