From f506de2cdaf92a5716298cf9d63cc686a1097a29 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 20 Sep 2018 10:06:49 +0200 Subject: [PATCH] ath9k: fix unloading the module Registering a GPIO chip with the ath9k device as parent prevents unload, because the gpiochip core increases the module use count. Unfortunately, the only way to avoid this at the moment seems to be to register the GPIO chip without a parent device Signed-off-by: Felix Fietkau --- .../patches/548-ath9k_enable_gpio_chip.patch | 17 ++++++----------- .../patches/549-ath9k_enable_gpio_buttons.patch | 8 ++++---- 2 files changed, 10 insertions(+), 15 deletions(-) diff --git a/package/kernel/mac80211/patches/548-ath9k_enable_gpio_chip.patch b/package/kernel/mac80211/patches/548-ath9k_enable_gpio_chip.patch index 31dac29ad7..0b76d330c6 100644 --- a/package/kernel/mac80211/patches/548-ath9k_enable_gpio_chip.patch +++ b/package/kernel/mac80211/patches/548-ath9k_enable_gpio_chip.patch @@ -45,7 +45,7 @@ Signed-off-by: Felix Fietkau #ifdef CPTCFG_ATH9K_DEBUGFS --- a/drivers/net/wireless/ath/ath9k/gpio.c +++ b/drivers/net/wireless/ath/ath9k/gpio.c -@@ -16,13 +16,135 @@ +@@ -16,13 +16,130 @@ #include "ath9k.h" #include @@ -126,11 +126,7 @@ Signed-off-by: Felix Fietkau + gc->sc = sc; + snprintf(gc->label, sizeof(gc->label), "ath9k-%s", + wiphy_name(sc->hw->wiphy)); -+#if LINUX_VERSION_CODE >= KERNEL_VERSION(4,5,0) -+ gc->gchip.parent = sc->dev; -+#else -+ gc->gchip.dev = sc->dev; -+#endif ++ + gc->gchip.label = gc->label; + gc->gchip.base = -1; /* determine base automatically */ + gc->gchip.ngpio = ah->caps.num_gpio_pins; @@ -145,7 +141,6 @@ Signed-off-by: Felix Fietkau + return; + } + -+ gc->gchip.owner = NULL; + sc->gpiochip = gc; +} + @@ -183,7 +178,7 @@ Signed-off-by: Felix Fietkau static void ath_fill_led_pin(struct ath_softc *sc) { struct ath_hw *ah = sc->sc_ah; -@@ -80,6 +202,12 @@ static int ath_add_led(struct ath_softc +@@ -80,6 +197,12 @@ static int ath_add_led(struct ath_softc else ath9k_hw_set_gpio(sc->sc_ah, gpio->gpio, gpio->active_low); @@ -196,7 +191,7 @@ Signed-off-by: Felix Fietkau return 0; } -@@ -136,17 +264,24 @@ void ath_deinit_leds(struct ath_softc *s +@@ -136,17 +259,24 @@ void ath_deinit_leds(struct ath_softc *s while (!list_empty(&sc->leds)) { led = list_first_entry(&sc->leds, struct ath_led, list); @@ -221,7 +216,7 @@ Signed-off-by: Felix Fietkau char led_name[32]; const char *trigger; int i; -@@ -156,6 +291,15 @@ void ath_init_leds(struct ath_softc *sc) +@@ -156,6 +286,15 @@ void ath_init_leds(struct ath_softc *sc) if (AR_SREV_9100(sc->sc_ah)) return; @@ -237,7 +232,7 @@ Signed-off-by: Felix Fietkau ath_fill_led_pin(sc); if (pdata && pdata->leds && pdata->num_leds) -@@ -180,6 +324,7 @@ void ath_init_leds(struct ath_softc *sc) +@@ -180,6 +319,7 @@ void ath_init_leds(struct ath_softc *sc) ath_create_gpio_led(sc, sc->sc_ah->led_pin, led_name, trigger, !sc->sc_ah->config.led_active_high); } diff --git a/package/kernel/mac80211/patches/549-ath9k_enable_gpio_buttons.patch b/package/kernel/mac80211/patches/549-ath9k_enable_gpio_buttons.patch index e86e3e38bd..e7282ab6b1 100644 --- a/package/kernel/mac80211/patches/549-ath9k_enable_gpio_buttons.patch +++ b/package/kernel/mac80211/patches/549-ath9k_enable_gpio_buttons.patch @@ -29,7 +29,7 @@ Signed-off-by: Felix Fietkau #ifdef CPTCFG_MAC80211_LEDS -@@ -129,6 +131,67 @@ static void ath9k_unregister_gpio_chip(s +@@ -124,6 +126,67 @@ static void ath9k_unregister_gpio_chip(s sc->gpiochip = NULL; } @@ -97,7 +97,7 @@ Signed-off-by: Felix Fietkau #else /* CONFIG_GPIOLIB */ static inline void ath9k_register_gpio_chip(struct ath_softc *sc) -@@ -139,6 +202,14 @@ static inline void ath9k_unregister_gpio +@@ -134,6 +197,14 @@ static inline void ath9k_unregister_gpio { } @@ -112,7 +112,7 @@ Signed-off-by: Felix Fietkau #endif /* CONFIG_GPIOLIB */ /********************************/ -@@ -262,6 +333,7 @@ void ath_deinit_leds(struct ath_softc *s +@@ -257,6 +328,7 @@ void ath_deinit_leds(struct ath_softc *s { struct ath_led *led; @@ -120,7 +120,7 @@ Signed-off-by: Felix Fietkau while (!list_empty(&sc->leds)) { led = list_first_entry(&sc->leds, struct ath_led, list); #ifdef CONFIG_GPIOLIB -@@ -301,6 +373,7 @@ void ath_init_leds(struct ath_softc *sc) +@@ -296,6 +368,7 @@ void ath_init_leds(struct ath_softc *sc) } ath_fill_led_pin(sc);
