Okay, but this comment block really needs reformatting to use the usual
block comment style, and with spaces to line up the columns instead of
tabs so it still looks okay when the " * " is removed from the start of
each line of the block comment.

Thanks for your comments for my patch 1~3. I will rework and resend the
3 patches.

When you resend patches, please let me know what version of the patch
series this is, with a "v2" or something in the subject area.
Right now I see a bunch of patches from you, but no clue as to which is
the 'latest' and what changed in what version.
So I'm going to drop them all, please resend.
Also, you don't need the kernel version in the [PATCH] area, as we are
always assuming you are making the patch against the latest kernel
version, hopefully my staging-testing branch, otherwise we couldn't
apply it no matter what.
thanks,

It shouldn't have a completely blank line there, it should either be
plugged up with a ' *' at the start, or the comment should be split into
two at that point.
Actually, most of the above part of the comment is pretty superfluous as
the information is effectively repeated in the part below. You could
remove all but the "file location" line.

Since you're reformatting this anyway, it would be better if all the
stuff below this point was shifted two spaces to the left as there is no
logical need for extra indentation here. Also, if you can expand any
tabs below, you can drop your patch 3.

Cc: devel, linux-kernel, wei.guo.simon
Correct one coding style problem(detected by checkpatch.pl) in pcl818.c.
- code indent should use tabs where possible
It is fixed by reformatting the comment block to usual comment style.

-Driver: pcl818
-Description: Advantech PCL-818 cards, PCL-718
-Author: Michal Dobes <dobes@tesnet.cz>
-Devices: [Advantech] PCL-818L (pcl818l), PCL-818H (pcl818h),
- PCL-818HD (pcl818hd), PCL-818HG (pcl818hg), PCL-818 (pcl818),
- PCL-718 (pcl718)
-Status: works
-
-All cards have 16 SE/8 DIFF ADCs, one or two DACs, 16 DI and 16 DO.
-Differences are only at maximal sample speed, range list and FIFO
-support.
-The driver support AI mode 0, 1, 3 other subdevices (AO, DI, DO) support
-only mode 0. If DMA/FIFO/INT are disabled then AI support only mode 0.
-PCL-818HD and PCL-818HG support 1kword FIFO. Driver support this FIFO
-but this code is untested.
-A word or two about DMA. Driver support DMA operations at two ways:
-1) DMA uses two buffers and after one is filled then is generated
- INT and DMA restart with second buffer. With this mode I'm unable run
- more that 80Ksamples/secs without data dropouts on K6/233.
-2) DMA uses one buffer and run in autoinit mode and the data are
- from DMA buffer moved on the fly with 2kHz interrupts from RTC.
- This mode is used if the interrupt 8 is available for allocation.
- If not, then first DMA mode is used. With this I can run at
- full speed one card (100ksamples/secs) or two cards with
- 60ksamples/secs each (more is problem on account of ISA limitations).
- To use this mode you must have compiled kernel with disabled
- "Enhanced Real Time Clock Support".
- Maybe you can have problems if you use xntpd or similar.
- If you've data dropouts with DMA mode 2 then:
- a) disable IDE DMA
- b) switch text mode console to fb.
