xen: remove setting of 'transp' parameter

[PATCH] xen: remove setting of 'transp' parameter

Posted by Tom Rix 3 years, 11 months ago

cppcheck reports
[drivers/video/fbdev/xen-fbfront.c:226]: (style) Assignment of function parameter has no effect outside the function.

The value parameter 'transp' is not used, so setting it can be removed.
