[PATCH] mtd: nand: omap2: Fix partition creation via cmdline mtdparts

commit c9711ec5250b ("mtd: nand: omap: Clean up device tree support") caused the parent device name to be changed from "omap2-nand.0" to ".nand" (e.g. 3000.nand on omap3 platforms). This caused mtd->name to be changed as well. This breaks partition creation via mtdparts passed by u-boot as it

[PATCH 1/3] tty: close race between device register and open

The tty class device is currently not registered until after the character device has been registered thereby leaving a small window were a racing open could end up with a NULL tty->dev pointer due to the class-device lookup failing in alloc_tty_struct. Close this race by registering the class

[PATCH 0/3] tty: close registration race and add termios reset feature

The first patch in this series closes a race between tty device registration and tty open due to the character device being registered before the class device has been registered. The second patch removes some obsolete references to termios_locked, and the final patch makes sure that any saved

[PATCH 3/3] tty: reset termios state on device registration

Free any saved termios data when registering a tty device so that the termios state is reset when reusing a minor number. This is useful for hot-pluggable buses such as USB where it does not make much sense to reuse saved termios data from an unrelated device when a new device is later plugged
