From: H Hartley Sweeten Date: Sat, 8 Sep 2012 00:40:06 +0000 (-0700) Subject: staging: comedi: me4000: remove struct me4000_ai_info X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ba8dfef57b07c9ed6684805e16041e69b42d484;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git staging: comedi: me4000: remove struct me4000_ai_info The me4000_aio_info in the boardinfo struct is used to indicate the number of analog input channels and a couple other details about them. Remove the extra struct and absorb the data into the boardinfo struct.
