Marks the functions gsm_cleanup_mux(), gsm_activate_mux(), gsm_free_mux(), gsm_alloc_mux() and gsm_change_mtu() as static in n_gsm.c because they are not used outside this file.
Also, drop the EXPORT_SYMBOL_GPL for the above mentioned functions because nothing else in the kernel calls them. This eliminates the following warnings in n_gsm.c: drivers/tty/n_gsm.c:2022:6: warning: no previous prototype for ‘gsm_cleanup_mux’ [-Wmissing-prototypes] drivers/tty/n_gsm.c:2076:5: warning: no previous prototype for ‘gsm_activate_mux’ [-Wmissing-prototypes] drivers/tty/n_gsm.c:2120:6: warning: no previous prototype for ‘gsm_free_mux’ [-Wmissing-prototypes] drivers/tty/n_gsm.c:2156:17: warning: no previous prototype for ‘gsm_alloc_mux’ [-Wmissing-prototypes] drivers/tty/n_gsm.c:2714:5: warning: no previous prototype for ‘gsm_change_mtu’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.khe...@gmail.com> --- drivers/tty/n_gsm.c | 14 +++++--------- 1 file changed, 5 insertions(+), 9 deletions(-) diff --git a/drivers/tty/n_gsm.c b/drivers/tty/n_gsm.c index c0f76da..6ca9fbb 100644 --- a/drivers/tty/n_gsm.c +++ b/drivers/tty/n_gsm.c @@ -2019,7 +2019,7 @@ static void gsm_error(struct gsm_mux *gsm, * and then shut down each device hanging up the channels as we go. */ -void gsm_cleanup_mux(struct gsm_mux *gsm) +static void gsm_cleanup_mux(struct gsm_mux *gsm) { int i; struct gsm_dlci *dlci = gsm->dlci[0]; @@ -2062,7 +2062,6 @@ void gsm_cleanup_mux(struct gsm_mux *gsm) kfree(txq); INIT_LIST_HEAD(&gsm->tx_list); } -EXPORT_SYMBOL_GPL(gsm_cleanup_mux); /** * gsm_activate_mux - generic GSM setup @@ -2073,7 +2072,7 @@ EXPORT_SYMBOL_GPL(gsm_cleanup_mux); * finally kick off connecting to DLCI 0 on the modem. */ -int gsm_activate_mux(struct gsm_mux *gsm) +static int gsm_activate_mux(struct gsm_mux *gsm) { struct gsm_dlci *dlci; int i = 0; @@ -2109,7 +2108,6 @@ int gsm_activate_mux(struct gsm_mux *gsm) gsm->dead = 0; /* Tty opens are now permissible */ return 0; } -EXPORT_SYMBOL_GPL(gsm_activate_mux); /** * gsm_free_mux - free up a mux @@ -2117,13 +2115,12 @@ EXPORT_SYMBOL_GPL(gsm_activate_mux); * * Dispose of allocated resources for a dead mux */ -void gsm_free_mux(struct gsm_mux *gsm) +static void gsm_free_mux(struct gsm_mux *gsm) { kfree(gsm->txframe); kfree(gsm->buf); kfree(gsm); } -EXPORT_SYMBOL_GPL(gsm_free_mux); /** * gsm_free_muxr - free up a mux @@ -2153,7 +2150,7 @@ static inline void mux_put(struct gsm_mux *gsm) * Creates a new mux ready for activation. */ -struct gsm_mux *gsm_alloc_mux(void) +static struct gsm_mux *gsm_alloc_mux(void) { struct gsm_mux *gsm = kzalloc(sizeof(struct gsm_mux), GFP_KERNEL); if (gsm == NULL) @@ -2185,7 +2182,6 @@ struct gsm_mux *gsm_alloc_mux(void) return gsm; } -EXPORT_SYMBOL_GPL(gsm_alloc_mux); /** * gsmld_output - write to link @@ -2711,7 +2707,7 @@ static void gsm_mux_rx_netchar(struct gsm_dlci *dlci, return; } -int gsm_change_mtu(struct net_device *net, int new_mtu) +static int gsm_change_mtu(struct net_device *net, int new_mtu) { struct gsm_mux_net *mux_net = (struct gsm_mux_net *)netdev_priv(net); if ((new_mtu < 8) || (new_mtu > mux_net->dlci->gsm->mtu)) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
