From: Xinming Hu <huxm@xxxxxxxxxxx> Wait for firmware dump complete in card remove function. For sdio interface, there are two diffenrent cases, card reset trigger sdio_work and firmware dump trigger sdio_work. Do code rearrangement for distinguish between these two cases. Signed-off-by: Xinming Hu <huxm@xxxxxxxxxxx> Signed-off-by: Amitkumar Karwar <akarwar@xxxxxxxxxxx> --- v2: 1. Get rid of reset_triggered flag. Instead split the code and use __mwifiex_sdio_remove() (Brian Norris/Dmitry Torokhov) 2. "v1 4/5 mwifiex: firmware dump code rearrangement.." is dropped. So rebased accordingly. v3: same as [v2,5/5]. The improvement of 'moving pcie_work to card struct' suggested by Brian is taken care in next patch. --- drivers/net/wireless/marvell/mwifiex/pcie.c | 6 +++++- drivers/net/wireless/marvell/mwifiex/sdio.c | 15 ++++++++++++--- 2 files changed, 17 insertions(+), 4 deletions(-) diff --git a/drivers/net/wireless/marvell/mwifiex/pcie.c b/drivers/net/wireless/marvell/mwifiex/pcie.c index dd8f7aa..c8e69a4 100644 --- a/drivers/net/wireless/marvell/mwifiex/pcie.c +++ b/drivers/net/wireless/marvell/mwifiex/pcie.c @@ -51,6 +51,9 @@ static int mwifiex_pcie_probe_of(struct device *dev) return 0; } +static void mwifiex_pcie_work(struct work_struct *work); +static DECLARE_WORK(pcie_work, mwifiex_pcie_work); + static int mwifiex_map_pci_memory(struct mwifiex_adapter *adapter, struct sk_buff *skb, size_t size, int flags) @@ -254,6 +257,8 @@ static void mwifiex_pcie_remove(struct pci_dev *pdev) if (!adapter || !adapter->priv_num) return; + cancel_work_sync(&pcie_work); + if (user_rmmod && !adapter->mfg_mode) { mwifiex_deauthenticate_all(adapter); @@ -2722,7 +2727,6 @@ static void mwifiex_pcie_work(struct work_struct *work) mwifiex_pcie_device_dump_work(save_adapter); } -static DECLARE_WORK(pcie_work, mwifiex_pcie_work); /* This function dumps FW information */ static void mwifiex_pcie_device_dump(struct mwifiex_adapter *adapter) { diff --git a/drivers/net/wireless/marvell/mwifiex/sdio.c b/drivers/net/wireless/marvell/mwifiex/sdio.c index 16d1d30..78f2cc9 100644 --- a/drivers/net/wireless/marvell/mwifiex/sdio.c +++ b/drivers/net/wireless/marvell/mwifiex/sdio.c @@ -46,6 +46,9 @@ */ static u8 user_rmmod; +static void mwifiex_sdio_work(struct work_struct *work); +static DECLARE_WORK(sdio_work, mwifiex_sdio_work); + static struct mwifiex_if_ops sdio_ops; static unsigned long iface_work_flags; @@ -220,7 +223,7 @@ static int mwifiex_sdio_resume(struct device *dev) * This function removes the interface and frees up the card structure. */ static void -mwifiex_sdio_remove(struct sdio_func *func) +__mwifiex_sdio_remove(struct sdio_func *func) { struct sdio_mmc_card *card; struct mwifiex_adapter *adapter; @@ -249,6 +252,13 @@ static int mwifiex_sdio_resume(struct device *dev) mwifiex_remove_card(adapter); } +static void +mwifiex_sdio_remove(struct sdio_func *func) +{ + cancel_work_sync(&sdio_work); + __mwifiex_sdio_remove(func); +} + /* * SDIO suspend. * @@ -2227,7 +2237,7 @@ static void mwifiex_recreate_adapter(struct sdio_mmc_card *card) * discovered and initializes them from scratch. */ - mwifiex_sdio_remove(func); + __mwifiex_sdio_remove(func); /* * Normally, we would let the driver core take care of releasing these. @@ -2568,7 +2578,6 @@ static void mwifiex_sdio_work(struct work_struct *work) mwifiex_sdio_card_reset_work(save_adapter); } -static DECLARE_WORK(sdio_work, mwifiex_sdio_work); /* This function resets the card */ static void mwifiex_sdio_card_reset(struct mwifiex_adapter *adapter) { -- 1.9.1
