[PATCH 0/2] usb: atm: ueagle-atm: debug message changes

[Mauricio Faria de Oliveira]

This series changes/removes some debug messages in the ueagle-atm driver.

Patch 1 adjusts the 'device found' message to debug level.
Patch 2 removes the function entry/exit debug messages.

With:

  # echo 1 >/sys/module/printk/parameters/ignore_loglevel
  # echo 2 >/sys/module/ueagle_atm/parameters/debug
  # echo 'file drivers/usb/atm/ueagle-atm.c +p' >/sys/kernel/debug/dynamic_debug/control

Changes:

  -usb 1-1: [ueagle-atm vdbg]  entering uea_probe

  -usb 1-1: [ueagle-atm] ADSL device founded vid (0X1039) pid (0X2101) Rev (0X2581): Eagle I
  +usb 1-1: [ueagle-atm dbg] uea_probe: ADSL device found with vid (0X1039) pid (0X2101) Rev (0X2581): Eagle I

  -usb 1-1: [ueagle-atm vdbg]  entering uea_load_firmware
   usb 1-1: [ueagle-atm] pre-firmware device, uploading firmware
   usb 1-1: [ueagle-atm] loading firmware ueagle-atm/eagleI.fw
  -usb 1-1: [ueagle-atm vdbg]  leaving  uea_load_firmware
   usb 1-1: Direct firmware load for ueagle-atm/eagleI.fw failed with error -2
   usb 1-1: Falling back to sysfs fallback for: ueagle-atm/eagleI.fw
   usb 1-1: USB disconnect, device number 2
  -usb 1-1: [ueagle-atm vdbg]  entering uea_disconnect
  -usb 1-1: [ueagle-atm vdbg]  leaving  uea_disconnect
  -usb 1-1: [ueagle-atm vdbg]  entering uea_upload_pre_firmware
   usb 1-1: [UEAGLE-ATM] firmware is not available
  -usb 1-1: [ueagle-atm vdbg]  leaving  uea_upload_pre_firmware

Final:

   usb 1-1: [ueagle-atm dbg] uea_probe: ADSL device found with vid (0X1039) pid (0X2101) Rev (0X2581): Eagle I
   usb 1-1: [ueagle-atm] pre-firmware device, uploading firmware
   usb 1-1: [ueagle-atm] loading firmware ueagle-atm/eagleI.fw
   usb 1-1: Direct firmware load for ueagle-atm/eagleI.fw failed with error -2
   usb 1-1: Falling back to sysfs fallback for: ueagle-atm/eagleI.fw
   usb 1-1: USB disconnect, device number 2
   usb 1-1: [UEAGLE-ATM] firmware is not available

[PATCH 1/2] usb: atm: ueagle-atm: use dev_dbg() for 'device found' message

[Mauricio Faria de Oliveira]

Convert dev_info() to dev_dbg().

Per 'Documentation/process/coding-style.rst':

  13) Printing kernel messages

  ...  When drivers are working properly they are quiet,
  so prefer to use dev_dbg/pr_debug unless something is wrong.

While in there, correct the verb form and add 'with' for clarity.

[PATCH 2/2] usb: atm: ueagle-atm: remove function entry/exit debug messages

[Mauricio Faria de Oliveira]

in favor of existing kernel-level function tracing mechanisms.
