Since it is only used with SDIO, just explicitly set the op to NULL in spi.c Signed-off-by: Luciano Coelho --- drivers/net/wireless/wl12xx/sdio.c | 18 +++++++++++++++++- drivers/net/wireless/wl12xx/spi.c | 3 ++- 2 files changed, 19 insertions(+), 2 deletions(-) diff --git a/drivers/net/wireless/wl12xx/sdio.c b/drivers/net/wireless/wl12xx/sdio.c index 58d0208..55dc6e3 100644 --- a/drivers/net/wireless/wl12xx/sdio.c +++ b/drivers/net/wireless/wl12xx/sdio.c @@ -51,6 +51,18 @@ static const struct sdio_device_id wl1271_devices[] = { }; MODULE_DEVICE_TABLE(sdio, wl1271_devices); +/* The max SDIO block size is 256 when working with tx padding to SDIO block */ +#define TX_PAD_SDIO_BLK_SIZE 256 + +static void wl1271_sdio_set_block_size(struct wl1271 *wl) +{ + wl->block_size = TX_PAD_SDIO_BLK_SIZE; + + sdio_claim_host(wl->if_priv); + sdio_set_block_size(wl->if_priv, TX_PAD_SDIO_BLK_SIZE); + sdio_release_host(wl->if_priv); +} + static inline struct sdio_func *wl_to_func(struct wl1271 *wl) { return wl->if_priv; @@ -166,6 +178,9 @@ static int wl1271_sdio_power_on(struct wl1271 *wl) sdio_claim_host(func); sdio_enable_func(func); + /* Set the default block size in case it was modified */ + sdio_set_block_size(func, 0); + out: return ret; } @@ -203,7 +218,8 @@ static struct wl1271_if_operations sdio_ops = { .power = wl1271_sdio_set_power, .dev = wl1271_sdio_wl_to_dev, .enable_irq = wl1271_sdio_enable_interrupts, - .disable_irq = wl1271_sdio_disable_interrupts + .disable_irq = wl1271_sdio_disable_interrupts, + .set_block_size = wl1271_sdio_set_block_size, }; static int __devinit wl1271_probe(struct sdio_func *func, diff --git a/drivers/net/wireless/wl12xx/spi.c b/drivers/net/wireless/wl12xx/spi.c index 2993715..2a57583 100644 --- a/drivers/net/wireless/wl12xx/spi.c +++ b/drivers/net/wireless/wl12xx/spi.c @@ -355,7 +355,8 @@ static struct wl1271_if_operations spi_ops = { .power = wl1271_spi_set_power, .dev = wl1271_spi_wl_to_dev, .enable_irq = wl1271_spi_enable_interrupts, - .disable_irq = wl1271_spi_disable_interrupts + .disable_irq = wl1271_spi_disable_interrupts, + .set_block_size = NULL, }; static int __devinit wl1271_probe(struct spi_device *spi) -- 1.7.1
