Subject: [PATCH 1/3] vt: use min() to limit intervals
Date: Mon, 16 Mar 2020 07:59:09 +0100 [thread overview]
Message-ID: <20200316065911.11024-1-jslaby@suse.cz> (raw)
Instead of awkward ternary operator with comparison, use simple min()
for blankinterval and vesa_off_interval.
No functional change intended and "objdump -d" proves that.
