tty: mxser: Remove unused ASYNC_SHARE_IRQ flag

2016-04-30T16:26:55Z

ASYNC*_SHARE_IRQ is no longer used; remove. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Replace ASYNC_INITIALIZED bit and update atomically

2016-04-30T16:26:55Z

Replace ASYNC_INITIALIZED bit in the tty_port::flags field with TTY_PORT_INITIALIZED bit in the tty_port::iflags field. Introduce helpers tty_port_set_initialized() and tty_port_initialized() to abstract atomic bit ops. Note: the transforms for test_and_set_bit() and test_and_clear_bit() are unnecessary as the state transitions are already mutually exclusive; the tty lock prevents concurrent open/close/hangup.

tty: Replace ASYNC_CHECK_CD and update atomically

2016-04-30T16:26:55Z

Replace ASYNC_CHECK_CD bit in the tty_port::flags field with TTY_PORT_CHECK_CD bit in the tty_port::iflags field. Introduce helpers tty_port_set_check_carrier() and tty_port_check_carrier() to abstract the atomic bit ops. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Replace ASYNC_CTS_FLOW bit and update atomically

2016-04-30T16:26:55Z

Replace ASYNC_CTS_FLOW bit in the tty_port::flags field with TTY_PORT_CTS_FLOW bit in the tty_port::iflags field. Add tty_port_set_cts_flow() helper to abstract the atomic bit ops. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Replace TTY_IO_ERROR bit tests with tty_io_error()

2016-04-30T16:26:55Z

Abstract TTY_IO_ERROR status test treewide with tty_io_error(). NB: tty->flags uses atomic bit ops; replace non-atomic bit test with test_bit(). Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: constify tty_port_operations structs

2016-02-07T07:31:08Z

Constifies tty_port_operations structures in the tty driver since they are not modified after their initialization. Detected and found using Coccinelle. Suggested-by: Julia Lawall Signed-off-by: Aya Mahfouz Signed-off-by: Greg Kroah-Hartman

tty: mxser: Remove ASYNC_CLOSING

2016-01-28T22:19:12Z

The tty core no longer provides ASYNC_CLOSING. Use private flag for same purpose, which is to clear the fifos at each and every interrupt during driver close(). The driver uses this sledgehammer approach because its close/shutdown sequence is hopelessly borked. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Use termios c_*flag macros

2016-01-28T22:13:44Z

Expressions of the form "tty->termios.c_*flag & FLAG" are more clearly expressed with the termios flags macros, I_FLAG(), C_FLAG(), O_FLAG(), and L_FLAG(). Convert treewide. Signed-off-by: Peter Hurley Acked-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

tty: mxser: Fix build warning introduced by dfc7b837c7f9 (Re: linux-next: build warning after merge of the tty.current tree)

2013-05-22T17:26:02Z

Fix build warning at mxser.c introduced by dfc7b837c7f9 (tty: mxser: fix usage of opmode_ioaddr) Signed-off-by: Matwey V. Kornilov Reported-by: kbuild test robot Reported-by: Stephen Rothwell Signed-off-by: Greg Kroah-Hartman

tty: mxser: fix usage of opmode_ioaddr

2013-05-21T17:26:05Z

mxser_port->opmode_ioaddr is initialized only for MOXA_MUST_MU860_HWID chips, but no precautions have been undertaken to prevent reading and writing to undefined port number. Signed-off-by: Matwey V. Kornilov Signed-off-by: Greg Kroah-Hartman
