Subject: USB: generic.c: remove dbg() tracing calls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=de5789e22bcb4f7365b08c80bf3cdc3ab0a624d3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

USB: generic.c: remove dbg() tracing calls

dbg() was used a lot a long time ago to trace code flow.  Now that we have
ftrace, this isn't needed at all, so remove these calls.
