Subject: [U-Boot] [PATCH 1/3] usb:g_dnl:f_thor: remove memset before memcpy
Date: Tue, 10 Jun 2014 08:50:31 +0200 [thread overview]

Hi Jeroen,
> since ALLOC_CACHE_ALIGN_BUFFER defines a pointer and not a
> buffer, the memset with sizeof(rqt) likely does something else
> then intended. Since there is a memcpy directly after it with
> the full size, drop the memset completely.
