If i2c device probing fails, then there is no driver to dereference after calling i2c_new_device(). Stop assuming that probing will always succeed, to avoid NULL pointer dereferences. We have an easier access to the driver anyway. Signed-off-by: NJean Delvare <khali@linux-fr.org> Tested-by: NTim Shepard <shep@alum.mit.edu> Cc: Colin Leroy <colin@colino.net>

When an ACPI resource conflict is detected, error messages are already printed by ACPI. There's no point in causing the driver core to print more error messages, so return one of the error codes for which no message is printed.

There is no point in implementing a detect callback for the LTC4215 and LTC4245, as these devices can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callbacks. This shrinks the binary module sizes by 36% and 46%, respectively.

A couple of people have hit the WARN_ON() in drivers/char/tty_io.c, tty_open() that is unhappy about seeing the tty line discipline go away during the tty hangup. See for example http://bugzilla.kernel.org/show_bug.cgi?id=14255 and the reason is that we do the tty_ldisc_halt() outside the ldisc_mutex in order to be able to flush the scheduled work without a deadlock with vhangup_work. However, it turns out that we can solve this particular case by - using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits for just the particular work, rather than synchronizing with any random outstanding pending work. This won't deadlock, since the buf.work we synchronize with doesn't care about the ldisc_mutex, it just flushes the tty ldisc buffers. - realize that for this particular case, we don't need to wait for any hangup work, because we are inside the hangup codepaths ourselves. so as a result we can just drop the flush_scheduled_work() entirely, and then move the tty_ldisc_halt() call to inside the mutex. That way we never expose the partially torn down ldisc state to tty_open(), and hold the ldisc_mutex over the whole sequence.

I was recently lucky enough to get a 64-CPU system. The processors actually have T-states, so my kernel log ends up with 64 lines like: ACPI: Processor [CPU0] (supports xx throttling states) This is pretty useless clutter because - this info is already available after boot from /proc/acpi/processor/CPUnn/throttling - there's also an ACPI_DEBUG_PRINT() in processor_throttling.c that gives the same info on boot for anyone who *really* cares. So just delete the code that prints the throttling states in processor_core.c.

The ACPI /proc write() code takes an unsigned length argument like any write() function, but then assigned it to a *signed* integer called "len". Only after this is a sanity check for len done to make it not larger than 4. Due to the type change a len < 0 is in principle also possible; this patch adds a check for this.
