a2436b22de [SERIAL] remove unneeded code from serial_core.c
This patch fixes an issue reported by Coverity in serial/serial_core.c

Error reported: Variable "&((info)->tty)->flags" tracked as NULL was passed to a
function that dereferences it.

The later statements in the function assumes 'info->tty != NULL', so this
check is not necessary.  Probably a 'BUG_ON(info->tty == NULL)' can be added.

9480e307cd [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks
In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

e6158b4a56 [ARM] 3002/1: Wrong parameter to uart_update_timeout() in drivers/serial/pxa.c
Patch from Lothar Wassmann

The function serial_pxa_set_termios() is calling uart_update_timeout()
with the baud rate divisor as third parameter, while
uart_update_timeout() expects the baud rate in this place.
This results in a bogus port->timeout which is proportional to the
baud rate.

d38e24e260 [PATCH] ioc4_serial: Remove bogus error message
This change removes a bogus error message from the IOC4 serial driver
interrupt handler.

This error message is bogus for two reasons.  First, it can never occur
given that current code takes care to initialize IOC4 in such a way that
these "unknown" interrupts could never occur.  Second, this code fails to
take into account that other drivers can share the IOC4 interrupt mechanism
through SA_SHIRQ, and thus this driver is not in-fact "all-knowing".

Finally, this error message triggers every time some "unknown" interrupt
occurs -- it's not rate limited or repetition limited in any way, thereby
effectively denying use of the console device.  Given its bogosity in the
first place, it's best to just get rid of it entirely.
