Hi, The following is my compile result: ... LD [M] sound/soc/codecs/snd-soc-ak4613.ko LD [M] sound/soc/generic/snd-soc-audio-graph-card.ko LD [M] sound/soc/generic/snd-soc-simple-card-utils.ko LD [M] sound/soc/generic/snd-soc-simple-card.ko LD [M] sound/soc/sh/rcar/snd-soc-rcar.ko ret:0 These patches are based on mainline , and my version is linux-4.18-rc5. Last week , I pulled my upstream branch to the latest. I didn't see error log in this version. By the way , this is my git tree --- git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git . Please tell me which tree could suitably develop patch for upstream. Thanks, Pengbo Mu -----Original Message----- From: kbuild test robot [mailto:lkp@xxxxxxxxx] Sent: 2018年7月23日 15:05 To: Pengbo Mu <pengbo.mu@xxxxxxx> Cc: kbuild-all@xxxxxx; Felipe Balbi <balbi@xxxxxxxxxx>; Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>; linux-kernel@xxxxxxxxxxxxxxx; linux-usb@xxxxxxxxxxxxxxx; Ran Wang <ran.wang_1@xxxxxxx>; Pengbo Mu <pengbo.mu@xxxxxxx> Subject: Re: [PATCH] usb: dwc3: call set incr burst type func() Hi Pengbo, Thank you for the patch!
