Subject: Re: [PATCH] drivers/net/usb/r8152: change rtl8152_system_suspend to
 be void function

Hi zhong,

Thank you for the patch! Perhaps something to improve:

url:    https://github.com/0day-ci/linux/commits/zhong-jiang/drivers-net-usb-r8152-change-rtl8152_system_suspend-to-be-void-function/20180809-111737

New smatch warnings:
drivers/net/usb/r8152.c:4447 rtl8152_suspend() error: uninitialized symbol 'ret'.

Old smatch warnings:
drivers/net/usb/r8152.c:4660 rtl8152_get_strings() error: memcpy() '*rtl8152_gstrings' too small (32 vs 416)
