[PATCH resend] pwm: Remove obsolete HAVE_PWM Kconfig symbol

[PATCH resend] pwm: Remove obsolete HAVE_PWM Kconfig symbol

[Sascha Hauer]

Before we had the PWM framework we used to have a barebone PWM api. The
HAVE_PWM Kconfig symbol used to be selected by the PWM drivers to specify
the PWM API is present in the kernel. Since the last legacy driver is gone
the HAVE_PWM symbol can go aswell.

Thierry as PWM maintainer has agreed to take this patch. Would be nice
to get some Acks from affected architectures. Russell, Ralf?

No replies for over two weeks and this looks simple enough, so I just
went ahead and applied it. Thanks,

Am I looking in the wrong place, or have you not pushed this for linux-next yet?
I still see all the HAVE_PWM symbols in today's -next.

I had pushed to the wrong tree. It should be in linux-next as of today.
