Subject: usb: gadget: f_thor: Allocate request up to THOR_PACKET_SIZE
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4cb3a0d9b130c7583562db618fb2167f1c82ffea;p=thirdparty%2Fu-boot.git

usb: gadget: f_thor: Allocate request up to THOR_PACKET_SIZE

Allocate request up to THOR_PACKET_SIZE not the ep0->maxpacket
as the descriptors data depend on the number of descriptors
and this 64 bytes were not enough and the buffer might overflow
which results in memalign failures later.
