[PATCH 1/2] usb: chipidea: udc: improve error handling on ep_queue

From: "Felipe F. Tonello" _ep_queue() didn't check for errors when using add_td_to_list() which can fail if dma_pool_alloc fails, thus causing a kernel panic when lastnode->ptr is NULL. Signed-off-by: Felipe F. Tonello --- drivers/usb/chipidea/udc.c | 26 +++--- 1 file

[PATCH 1/2] usb: chipidea: udc: improve error handling on ep_queue

From: "Felipe F. Tonello" _ep_queue() didn't check for errors when using add_td_to_list() which can fail if dma_pool_alloc fails, thus causing a kernel panic when lastnode->ptr is NULL. Signed-off-by: Felipe F. Tonello ---
