[PATCH v2] staging: comedi: ni_*: Fix style warnings.
From: Aniruddha Shastri
Date: Thu Dec 14 2017 - 01:28:52 EST
Three of these warnings are now line-too-long warnings. I think these
warnings are preferable to the ones listed below. The longest line
is only 87 chars wide, which is reasonable.
Warnings fixed:
ni_670x.c:212: WARNING: struct comedi_lrange should normally be const
ni_atmio.c:239: WARNING: Avoid multiple line dereference
- prefer 'ni_boards[i].isapnp_id'
ni_labpc_common.c:573: WARNING: Avoid multiple line dereference
- prefer 'cmd->scan_begin_arg'
ni_mio_common.c:736: WARNING: Avoid multiple line dereference
- prefer 'devpriv->counter_dev->counters[gpct_index]'
ni_mio_common.c:1977: WARNING: Prefer using '"%s...", __func__'
to using 'ni_cmd_set_mite_transfer', this function's name, in a string
ni_mio_common.c:1990: WARNING: Prefer using '"%s...", __func__'
to using 'ni_cmd_set_mite_transfer', this function's name, in a string
ni_mio_common.c:4302: WARNING: function definition argument
'int' should also have an identifier name
ni_mio_common.c:4302: WARNING: function definition argument
'int' should also have an identifier name
ni_mio_common.c:4302: WARNING: function definition argument
'int *' should also have an identifier name
ni_mio_common.c:4699: WARNING: Prefer using '"%s...", __func__'
to using 'cs5529_do_conversion', this function's name, in a string
ni_stc.h:21: WARNING: Block comments should align the * on each line

Changes in v2:
No longer go out of our way to fix minor line-length violations at the expense
of code quality.
