3.11.10.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Colin Leitner <colin.leitner at googlemail.com>

commit 711fbdfbf2bc4827214a650afe3f64767a1aba16 upstream.

This patch removes an erroneous check of CSIZE, which made it impossible to set
CS5.

Compiles clean, but couldn't test against hardware.
