This is a patch to ks_hostif.c file that fixes up a checkpatch.pl
WARNING: void function return statements are not generally useful.
The 'return' statement is not useful here, because it is not necessary to be
forced the exit of the function.
Like in this example:
void funct() {
if(condition) return;
//do something;
}

It is an example when we can use 'return' from a void function, but now I think that is too much information and I will send patch v2 without it. mihaela > > Signed-off-by: Mihaela Muraru <mihaela.muraru21@gmail.com> > > --- > > drivers/staging/ks7010/ks_hostif.c | 8 -------- > > 1 file changed, 8 deletions(-) > > > > diff --git a/drivers/staging/ks7010/ks_hostif.c b/drivers/staging/ks7010/ks_hostif.c > > index 8798b63..5ae013b 100644 > > --- a/drivers/staging/ks7010/ks_hostif.c > > +++ b/drivers/staging/ks7010/ks_hostif.c > > @@ -1933,7 +1933,6 @@ void hostif_sme_set_wep(struct ks_wlan_private *priv, int type) > > break; > > } > > > > - return; > > } > > > > struct wpa_suite_t { > > @@ -2122,7 +2121,6 @@ void hostif_sme_set_rsn(struct ks_wlan_private *priv, int type) > > break; > > > > } > > - return; > > } > > > > static > > @@ -2236,7 +2234,6 @@ void hostif_sme_mode_setup(struct ks_wlan_private *priv) > > break; > > } > > > > - return; > > } > > > > static > > @@ -2337,7 +2334,6 @@ void hostif_sme_powermgt_set(struct ks_wlan_private *priv) > > } > > hostif_power_mngmt_request(priv, mode, wake_up, receiveDTIMs); > > > > - return; > > } > > > > static > > @@ -2355,7 +2351,6 @@ void hostif_sme_sleep_set(struct ks_wlan_private *priv) > > break; > > } > > > > - return; > > } > > > > static > > @@ -2413,7 +2408,6 @@ void hostif_sme_set_key(struct ks_wlan_private *priv, int type) > > &priv->wpa.key[2].rx_seq[0]); > > break; > > } > > - return; > > } > > > > static > > @@ -2649,7 +2643,6 @@ void hostif_sme_task(unsigned long dev) > > tasklet_schedule(&priv->sme_task); > > } > > } > > - return; > > } > > > > /* send to Station Management Entity module */ > > @@ -2733,5 +2726,4 @@ int hostif_init(struct ks_wlan_private *priv) > > void hostif_exit(struct ks_wlan_private *priv) > > { > > tasklet_kill(&priv->sme_task); > > - return; > > } > > -- > > 2.7.4 > > > > -- > > You received this message because you are subscribed to the Google Groups "outreachy-kernel" group. > > To unsubscribe from this group and stop receiving emails from it, send an email to outreachy-kernel+unsubscribe@googlegroups.com. > > To post to this group, send email to outreachy-kernel@googlegroups.com. > > To view this discussion on the web visit https://groups.google.com/d/msgid/outreachy-kernel/20161007215439.GA15407%40domino-MS-16Y1. > > For more options, visit https://groups.google.com/d/optout. > > ^ permalink raw reply [flat|nested] 4+ messages in thread
