[patch v4 1/3] tty: add function to convert device name to number

The function converts strings like ttyS0 and ttyUSB0 to dev_t like (4, 64) and (188, 0). It does this by scanning tty_drivers list for corresponding device name and index. If the driver is not registered, this function returns -ENODEV. It also acquires tty_mutex. Signed-off-by: Okash Khawaja

[PATCH v4 2/3] tracing: Add support for display of tgid in trace output
