Peter Chen 4dab0fd403 usb: cdns3: gadget: suspicious implicit sign extension ... [ Upstream commit 5fca3f0628 ] The code: trb->length = cpu_to_le32(TRB_BURST_LEN(priv_ep->trb_burst_size) | TRB_LEN(length)); TRB_BURST_LEN(priv_ep->trb_burst_size) may be overflow for int 32 if priv_ep->trb_burst_size is equal or larger than 0x80; Below is the Coverity warning: sign_extension: Suspicious implicit sign extension: priv_ep->trb_burst_size with type u8 (8 bits, unsigned) is promoted in priv_ep->trb_burst_size << 24 to type int (32 bits, signed), then sign-extended to type unsigned long (64 bits, unsigned). If priv_ep->trb_burst_size << 24 is greater than 0x7FFFFFFF, the upper bits of the result will all be 1. To fix it, it needs to add an explicit cast to unsigned int type for ((p) << 24).
