scanning for trivial bug-patters with coccinelle spatches returned:
./drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c:1395
WARNING: condition with no effect (if branch == else)
drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c - line numbers from 4.1-rc7
1395 if (bWithoutHWSM) {
1396 /* value16 |= (APDM_HOST | FSM_HSUS |/PFM_ALDN); */
1397 /* 2010/08/31 According to Filen description, we need to
1398 use HW to shut down 8051 automatically. */
1399 /* Because suspend operation need the asistance of 8051
1400 to wait for 3ms. */
1401 value16 = APDM_HOST | AFSM_HSUS | PFM_ALDN;
1402 } else {
1403 value16 = APDM_HOST | AFSM_HSUS | PFM_ALDN;
1404 }
1405
1406 rtl8723au_write16(padapter, REG_APS_FSMCO, value16); /* 0x4802 */
Not clear what the intent is but this looks like a typo/bug in the assigment
of value16 as the condition here has no effect.
thx!
