Subject: Re: [PATCH] media: cxusb-analog: Use ARRAY_SIZE for
 cxusub_medion_pin_config

Hi Maciej,

Thank you for the patch, but I posted a fix for this earlier already:

https://patchwork.linuxtv.org/patch/56441/

I'll drop this patch in favor of the one above. Apologies for not
CC-ing you on my patch, I should have done that.

Regards,

	Hans
