From 58f99df448501041a8092b281ff7adf0bd4f38ac Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Wed, 15 Apr 2015 13:42:19 +0200 Subject: [PATCH] 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.
