drm/atmel-hlcdc: check stride values in the first plane
The statement always evaluates to true since the struct fields are arrays. This has shown up as a warning when compiling with clang: warning: address of array 'desc->layout.xstride' will always evaluate to 'true' [-Wpointer-bool-conversion] Check for values in the first plane instead.
