Re: [PATCH] pwm: core: cleanup pointer tests

Hey list, After working on a new pwm-driver I noticed that not everybody actually has the set_polarity op and thus its an optional property. For a moment I figured I could add a 'software' polarity function by inverting the calculation of the on/off time, but I don't even have the hardware to

[PATCH] pwm: core: cleanup pointer tests

From: Olliver Schinagl pwm_set_polarity() checks if there's ops and polarity function pointers. Most of these pointers are actually checked when a chip is added via pwm_add, except for set_polarity. This patch adds set_polarity to the list of functions to test on pwmchip_add_with_polarity(); and
