__FUNCTION__ and __PRETTY_FUNCTION__ are gcc extensions that predate
the C99 __func__ identifier. scripts/checkpatch.pl emits a warning
for any new use of __FUNCTION__ and recommends __func__ instead. In
C (unlike C++) __PRETTY_FUNCTION__ is identical to __func__ because
C function names do not carry signature information, so the
distinction has no behavioural effect here. The majority of the tree
already uses __func__, but a handful of older files in arch/, board/,
boot/, drivers/, examples/ and include/ still carry the gcc spellings
(55 occurrences of __FUNCTION__ across 19 files plus one
__PRETTY_FUNCTION__ in drivers/usb/musb-new/omap2430.c). Convert
them all to the C99 form so the tree is consistent and new patches
in these areas do not have to follow an outdated local style.
Ten "Unnecessary ftrace-like logging - prefer using ftrace" warnings
remain on the printf("%s\n", __func__) and dbg("%s\n", __func__)
function-entry traces in drivers/net/rtl8169.c (behind DEBUG_RTL8169*
preprocessor guards) and drivers/usb/host/ohci-hcd.c. checkpatch
matches the literal "%s\n", __func__ shape regardless of the wrapper,
so silencing those warnings would require changing the debug message
text or removing the traces entirely.
