Subject: Re: [PATCH] media: soc-camera: increase the length of clk_name on
 soc_of_bind()

Hi Josh,

Sorry, I missed the 4.3 merge cycle, but isn't this patch a fix? Isn't it 
fixing soc-camera / atmel-isi on a specific platform, where the clock name 
is longer, than currently supported? Is this platform in the mainline and 
its current camera support is broken because of this? In such a case we 
could still push it in for 4.3

Thanks
Guennadi
