As of commit ebd2c8f6 ("serial: kill off uart_info"), the circular transmission buffer is part of struct uart_state instead of struct uart_info. Make it clear this structure is pointed to from struct uart_port. Change 'circ' to 'circ_buf' to match the structure name while we're at it. Signed-off-by:

Stop referring to the mutex member of the tty_port struct as 'port->mutex', as 'port' is ambiguous, and usually refers to the uart_port struct in this document. Use 'tty_port->mutex' instead, following the single existing use. Signed-off-by:

A small bug with the new autoksyms support showed that there are two kernel modules in the Documentation directory that qualify as samples, while all other samples are in the samples/ directory. This patch was originally meant as a workaround for that bug, but it has now been solved in a different way. However, I still think it makes sense as a cleanup to consolidate all sample code in one place. Signed-off-by:
