Subject: staging: comedi: dt3000: remove dev_dbg() noise
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f26d8b70b4ac22646388b7c58ec3d9f97d4e0f9f;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

staging: comedi: dt3000: remove dev_dbg() noise

Remove most of the dev_dbg() output from this driver. Most of it
is just noise.

For now I have left the dev_dbg() in the dt3k_send_cmd() function.
I still have not quite figured out how the low-level i/o works in
this driver...
