[Intel-gfx] [PATCH 0/4] Detect and remove trace_printk

[Nicolas Boichat]

trace_printk is meant as a debugging tool, and should not be
compiled into production code without specific debug Kconfig
options enabled or source code changes.

Patches 1 to 3 remove/disable trace_printk that should not
be enabled by default.

Patch 4 adds a config option that can be used to detect such
trace_printk at compile time (instead of printing a nasty
warning at runtime).

Nicolas Boichat (4):
  usb: cdns3: gadget: Replace trace_printk by dev_dbg
  media: atomisp: Replace trace_printk by pr_info
  media: camss: vfe: Use trace_printk for debugging only
  kernel/trace: Add TRACING_ALLOW_PRINTK config option
