Subject: [SERIAL]: Avoid 'statement with no effect' warnings.
X-Git-Tag: v2.6.14-rc1~528^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=93c37f292110a37dd77e4cc0aaf1c341d79bf6aa;p=pandora-kernel.git

[SERIAL]: Avoid 'statement with no effect' warnings.

When SUPPORT_SYSRQ is false, gcc can emit warnings for
the uart_handle_sysrq_char() that results.  Using an
empty inline returning zero kills the warning.
