2008-06-06serial: fix driver_name conflictsAnton Vorontsov
Some drivers are using too generic "serial" name for driver_name, this might cause issues, like this: Freescale QUICC Engine UART device driver proc_dir_entry 'serial' already registered Call Trace: [cf82de50] [c0007f7c] show_stack+0x4c/0x1ac (unreliable) [cf82de90] [c00b03fc] proc_register+0xfc/0x1ac [cf82dec0] [c00b05c8] create_proc_entry+0x60/0xac [cf82dee0] [c00b23dc] proc_tty_register_driver+0x60/0x98 [cf82def0] [c016dbd8] tty_register_driver+0x1b4/0x228 [cf82df20] [c0184d70] uart_register_driver+0x144/0x194 [cf82df40] [c030a378] ucc_uart_init+0x2c/0x94 [cf82df50] [c02f21a0] kernel_init+0x98/0x27c [cf82dff0] [c000fa74] kernel_thread+0x44/0x60 ^^ The board is using ucc_uart.c and 8250.c, both registered as "serial". This patch fixes two drivers that are using "serial" for driver_name and not "ttyS" for dev_name. Drivers that are using "ttyS" for dev_name, will conflict anyway, so we don't bother with these.

2008-06-06modedb: fix incorrect sync and vmode flags for CVT modesKrzysztof Helt
The temporary structure for calculated CVT mode is not initialized. Few fields have only bits or-ed or and-ed so they may be left in incorrect (random) state. Testing of the tridentfb seems like a good exercise for the fbdev layer.

2008-06-06md: do not compute parity unless it is on a failed driveDan Williams
If a block is computed (rather than read) then a check/repair operation may be lead to believe that the data on disk is correct, when infact it isn't. So only compute blocks for failed devices. This issue has been around since at least 2.6.12, but has become harder to hit in recent kernels since most reads bypass the cache. echo repair > /sys/block/mdN/md/sync_action will set the parity blocks to the correct state.

2008-06-06md: fix prexor vs sync_request raceDan Williams
During the initial array synchronization process there is a window between when a prexor operation is scheduled to a specific stripe and when it completes for a sync_request to be scheduled to the same stripe. When this happens the prexor completes and the stripe is unconditionally marked "insync", effectively canceling the sync_request for the stripe. Prior to 2.6.23 this was not a problem because the prexor operation was done under sh->lock. The effect in older kernels being that the prexor would still erroneously mark the stripe "insync", but sync_request would be held off and re-mark the stripe as "!in_sync". Change the write completion logic to not mark the stripe "in_sync" if a prexor was performed. The effect of the change is to sometimes not set STRIPE_INSYNC. The worst this can do is cause the resync to stall waiting for STRIPE_INSYNC to be set. If this were happening, then STRIPE_SYNCING would be set and handle_issuing_new_read_requests would cause all available blocks to eventually be read, at which point prexor would never be used on that stripe any more and STRIPE_INSYNC would eventually be set. echo repair > /sys/block/mdN/md/sync_action will correct arrays that may have lost this race.

2008-06-06spi: fix refcount-related spidev oops-on-rmmodDavid Brownell
This addresses other oopsing paths in "spidev" by changing how it manages refcounting. It decouples the lifecycle of the per-device data from the class device (not just the spi device): - Use class_{create,destroy} not class_{register,unregister}. - Use device_{create,destroy} not device_{register,unregister}. - Free the per-device data only when TWO conditions are true: * Driver is unbound from underlying SPI device, and * Device is no longer open (new) Also, spi_{get,set}_drvdata not dev_{get,set}_drvdata for simpler code.

This problem can probably be worked around in other ways as well, i went for the minimal fix. Obviously, the kconfig tool should be fixed, it is not reasonable to expect driver authors to do manual dependency resolution (that kconfig itself already does) and uglify the Kconfig files. The kconfig tool did nothing to warn about this situation and did not prevent this faulty .config from being constructed.
