From: Ian Abbott Date: Wed, 16 Oct 2013 13:40:08 +0000 (+0100) Subject: staging: comedi: adl_pci9111: sample types are unsigned X-Git-Tag: v3.13-rc1~170^2~247 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b909ba8f8bbeda364e86cca728d7a9a325233fd6;p=kernel%2Fkernel-generic.git staging: comedi: adl_pci9111: sample types are unsigned Sample values in comedi are generally represented as unsigned values. Change the element type of the `ai_bounce_buffer[]` member of `struct pci9111_private_data` from `short` to `unsigned short` for consistency. Also change the type of the `array` variable in `pci9111_ai_munge()` from `short *` to `unsigned short *`.
