Subject: hvc_console: Always schedule resize work on resize
X-Git-Tag: v2.6.29-rc1~574^2~88
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=7947cf0dd4b6a2bb06c57971502fb81c76a66f2d;p=~shefty%2Frdma-dev.git

hvc_console: Always schedule resize work on resize

The test to check for a new winsize runs out-of-sync with the
underlying tty.  After a tty has been released and initialized again,
the winsize might differ between the tty and the hp struct.  The
solution is to simply remove the check and always schedule the resize
work.
