X-Git-Tag: MMI-PSA29.97-13-9~14152^2~769
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=70d52bce5523f2c6a7bf3f9a54dacc0be112a3e8;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

staging: comedi: ni_labpc: remove range_labpc_1200_ai export

The 'ai_range_table' boardinfo is only used to initialize the
analog input subdevice s->range_table. We can use the 'is_labpc1200'
flag in the boardinfo to determine which range table is needed.

This allows making range_labpc_1200_ai static and removing the
export as well as removing the 'ai_range_table' from the boardinfo.
