[PATCH 6/6] staging: r8188eu: Remove _func_enter and _func_exit macros

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



These debugging macros are seldom used for debugging once the driver
is working. If routine tracing is needed, it can be added on an
individual basis.

In a few cases, removal of the exit macro left a bare label. In these
cases, a go to that label was replaced by a return.
