[PATCH 3.2 117/185] USB: spcp8x5: correct handling of CS5 setting

[Ben Hutchings]

3.2.54-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Colin Leitner <colin.leitner@xxxxxxxxxxxxxx>

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.
