serial: fix platform driver hotplug/coldplug

2008-04-16T02:35:40Z

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable serial platform drivers, to re-enable auto loading. NOTE that Kconfig for some of these drivers doesn't allow modular builds, and thus doesn't match the driver source's unload support. Presumably their unload code is buggy and/or weakly tested...

atmel_serial: fix uart/console concurrent access

2008-04-02T22:28:19Z

Strange chars appear on the serial port when a printk and a printf happens at the same time. This is caused by the pdc sending chars while atmel_console_write (called from printk) is executing Concurent access of uart and console to the same port leads to corrupted data to be transmitted, so disable tx dma (PDC) while writing to the console.

atmel_serial: avoid stopping pdc during transmission

2008-04-02T22:28:19Z

I found a problem related to losing data during pdc transmission in atmel_serial: connect ttyS1 with ttyS2 using a loopback cable, send 30 byte of packet from one to the other and waiting for 30 byte. On the other side just read and echo the data received. We always call atmel_tx_dma() from the tasklet regardless of what interrupt triggered it.

serial: sh-sci: Fix fifo stall on SH7760/SH7780/SH7785 SCIF.

2008-03-11T04:58:50Z

There was an off-by-1 in the SCRFDR calculation that caused writes over 128-bytes to hang in the FIFO. Fix it up. Signed-off-by: Yutaro Ebihara Signed-off-by: Paul Mundt

of_serial: fix section mismatch warnings

2008-03-11T01:01:17Z

Fix the following section mismatches: WARNING: drivers/built-in.o(.exit.text+0x5a): Section mismatch in reference from the function of_platform_serial_exit() to the variable .devinit.data:of_platform_serial_driver The function __exit of_platform_serial_exit() references a variable __devinitdata of_platform_serial_driver.

drivers/serial/m32r_sio.c: correct use of ! and &

2008-03-05T00:35:16Z

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337 ("wmi: (!x & y) strikes again"), a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // Signed-off-by: Julia Lawall Cc: Hirokazu Takata Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
