Hello there, [linux-4.4-rc8/arch/mips/include/asm/netlogic/xlr/fmn.h:304]: (style) Expression '(X & 0x2) == 0x1' is always false. Source code is if ((status & 0x2) == 1) pr_info("Send pending fail!\n"); Maybe better code if ((status & 0x2) != 0) pr_info("Send pending fail!\n"); Regards David Binderman
