* [MTD] Fix dependencies for MIPS MTD driversRalf Baechle2007-04-171-3/+3
| | | | | | | | | | | o A dependency on the processor architecture does not make sense; delete it. o The Alchemy and MTX drivers requires MTD_PARTITIONS and MTD_CFI to work, make those dependencies.

| * [PATCH] [MTD] block2mtd: remove readahead codeJoern Engel2007-02-201-53/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Over the years there was a slow trickle of complaints against the readahead code. Most of them concerned performance, Peter Zijlstra stumbled over it when working unrelated changes and I believe there was an actual bug report. Oh, Andrew Morton also complained about duplicating code from mm/readahead.c. It is just not worth it. On flash media like usb sticks, readahead will make things go slow - very slow. On spinning disks, readahead may be a win, but this is definitely not the place to add it. Signed-off-by: Jörn Engel <joern@lazybastard.org>

I will rework the ability for sysfs to change layouts like this in the future, but for now, this patch should fix people's network connections.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is a patch adding the PID for the FT232RL to ftdi_sio. The patch generates a warning during compilation because get_ftdi_divisor doesn't explicitly handle the FT232RL with this patch, so I guess you don't want to use it in its current state. It is all I could come up with with the knowledge I have of the drivers at the moment, though, and I hope you can have some use for it at least. It works fine with my DLP-TILT with an FT232RL.

| * | | USB: RTS/DTR signal patch for airprime driverMartin Schiller2007-03-091-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I encountered some problems with the airprime driver in use with a Novatel Merlin XU870: Closing an open Connection to e.g. /dev/ttyUSB0 doesn't reset the RTS/DTR lines of the Modem. Consequently, when I use minicom to establish a connection by "ATD*99#" the modem doesn't hang up even if i exit minicom and so I cannot reuse the modem unless I remove it and plug it in again. With the attached patch, the RTS/DTR lines are resetted on a close. The code was mainly taken from the option.c driver.

Do this with a perpetually incrementing "event_count" to detect when a new event occurs and it is safe to read status. There is no workaround for polling mode -- it is inherently exposed to reading and acting on stale status, since it doesn't have an interrupt to tell it the event completed. http://bugzilla.kernel.org/show_bug.cgi?id=8110 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
