Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

Caused by commit 0c2498f16608 ("pwm: Add PWM framework support"). There
are (e.g.) definitions of pwm_free in arch/mips/jz4740/pwm.c,
arch/unicore32/kernel/pwm.c, drivers/mfd/twl6030-pwm.c,
drivers/misc/ab8500-pwm.c and now drivers/pwm/core.c. Four of these are
EXPORTed.

I have just left this broken for today - please investigate a solution
quickly.
