From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
hwdesc is being initialized to desc->hwdesc but this is never read
as hwdesc is overwritten in a for-loop. Remove the redundant
initialization and move the declaration of hwdesc into the for-loop.
Cleans up clang warning:
Value stored to 'hwdesc' during its initialization is never read
