2012-01-27serial: Kill off NO_IRQAlan Cox1-1/+1
We transform the offenders into a test of irq <= 0 which will be ok while the ARM people get their platform sorted. Once that is done (or in a while if they don't do it anyway) then we will change them all to !irq checks. For arch specific drivers that are already using NO_IRQ = 0 we just test against zero so we don't need to re-review them later.

2011-11-24drivers/serial/ucc_uart.c: Add missing call to init UCC UART port timeoutChuck Meade1-0/+3
The UCC UART driver is missing a call to uart_update_timeout(). Without this call, attempting to close the port after outputting large amounts of data (i.e. using tty and uart buffering) results in long timeouts before the port will actually be shut down. For example, cat a large file to a UCC UART port. With the current driver, the port will stay open for 30 seconds after the last byte of data is output. But with this patch, the port is closed as expected, just after the data has been output (tx fifos empty).

2011-09-23TTY: serial, fix includes in some driversJiri Slaby1-1/+3
linux/tty_flip.h is included in linux/serial_core.h. But this may (and will) change in the future. Then we would get build errors such as: .../tty/serial/max3107.c: In function ‘put_data_to_circ_buf’: .../tty/serial/max3107.c:149:2: error: implicit declaration of function ‘tty_insert_flip_string’ So fix all the drviers which call tty flip buffer helpers to really include linux/tty_flip.h. And also make sure that those include linux/tty.h when operating with struct tty_struct.

2011-03-15drivers/serial/ucc_uart.c: Add of_node_put to avoid memory leakJulia Lawall1-32/+35
Add a call to of_node_put in the error handling code following a call to of_find_compatible_node or of_find_node_by_type. This patch also substantially reorganizes the error handling code in the function, to that it is possible first to jump to code that frees qe_port and then to jump to code that also puts np. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E,E1,E2; statement S; @@ *x = (of_find_node_by_path |of_find_node_by_name |of_find_node_by_phandle |of_get_parent |of_get_next_parent |of_get_next_child |of_find_compatible_node |of_match_node |of_find_node_by_type |of_find_node_with_property |of_find_matching_node |of_parse_phandle )(...); ... if (x == NULL) S <... when != x = E *if (...) { ... when != of_node_put(x) when != if (...) { ... of_node_put(x); ... } ( return <+...x...+>; | * return ...; ) } ...> ( E2 = x; | of_node_put(x); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Timur Tabi <timur@freescale.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Get rid of users of of_platform_driver in drivers/serial. The of_platform_{,un}register_driver functions are going away, so the users need to be converted to using the platform_bus_type directly. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Reviewed-by: Arnd Bergmann <arnd@arndb.de>
2011-01-13tty: move drivers/serial/ to drivers/tty/serial/Greg Kroah-Hartman1-0/+1537
The serial drivers are really just tty drivers, so move them to drivers/tty/ to make things a bit neater overall. This is part of the tty/serial driver movement proceedure as proposed by Arnd Bergmann and approved by everyone involved a number of months ago.
