This makes the code a bit smaller and also keeps sparse happy. Fixes the following sparse warnings: drivers/staging/iio/meter/ade7753.c:97:29: warning: incorrect type in argument 1 (different base types) drivers/staging/iio/meter/ade7753.c:97:29: expected restricted __be16 const [usertype] *p drivers/staging/iio/meter/ade7753.c:97:29: got unsigned short [usertype] *val drivers/staging/iio/meter/ade7754.c:97:29: warning: incorrect type in argument 1 (different base types) drivers/staging/iio/meter/ade7754.c:97:29: expected restricted __be16 const [usertype] *p drivers/staging/iio/meter/ade7754.c:97:29: got unsigned short [usertype] *val drivers/staging/iio/meter/ade7759.c:97:29: warning: incorrect type in argument 1 (different base types) drivers/staging/iio/meter/ade7759.c:97:29: expected restricted __be16 const [usertype] *p drivers/staging/iio/meter/ade7759.c:97:29: got unsigned short [usertype] *val Signed-off-by: Lars-Peter Clausen Acked-by: Jonathan Cameron Signed-off-by: Mark Brown --- diff --git a/drivers/staging/iio/meter/ade7753.c b/drivers/staging/iio/meter/ade7753.c index 74025fbae679..abfc8bd1794d 100644 --- a/drivers/staging/iio/meter/ade7753.c +++ b/drivers/staging/iio/meter/ade7753.c @@ -86,7 +86,7 @@ static int ade7753_spi_read_reg_16(struct device *dev, struct ade7753_state *st = iio_priv(indio_dev); ssize_t ret; - ret = spi_w8r16(st->us, ADE7753_READ_REG(reg_address)); + ret = spi_w8r16be(st->us, ADE7753_READ_REG(reg_address)); if (ret < 0) { dev_err(&st->us->dev, "problem when reading 16 bit register 0x%02X", reg_address); @@ -94,7 +94,6 @@ static int ade7753_spi_read_reg_16(struct device *dev, } *val = ret; - *val = be16_to_cpup(val); return 0; } diff --git a/drivers/staging/iio/meter/ade7754.c b/drivers/staging/iio/meter/ade7754.c index f649ebe55a04..3d1c02cd6538 100644 --- a/drivers/staging/iio/meter/ade7754.c +++ b/drivers/staging/iio/meter/ade7754.c @@ -86,7 +86,7 @@ static int ade7754_spi_read_reg_16(struct device *dev, struct ade7754_state *st = iio_priv(indio_dev); int ret; - ret = spi_w8r16(st->us, ADE7754_READ_REG(reg_address)); + ret = spi_w8r16be(st->us, ADE7754_READ_REG(reg_address)); if (ret < 0) { dev_err(&st->us->dev, "problem when reading 16 bit register 0x%02X", reg_address); @@ -94,7 +94,6 @@ static int ade7754_spi_read_reg_16(struct device *dev, } *val = ret; - *val = be16_to_cpup(val); return 0; } diff --git a/drivers/staging/iio/meter/ade7759.c b/drivers/staging/iio/meter/ade7759.c index d214ac4932cb..7467e51fd424 100644 --- a/drivers/staging/iio/meter/ade7759.c +++ b/drivers/staging/iio/meter/ade7759.c @@ -86,7 +86,7 @@ static int ade7759_spi_read_reg_16(struct device *dev, struct ade7759_state *st = iio_priv(indio_dev); int ret; - ret = spi_w8r16(st->us, ADE7759_READ_REG(reg_address)); + ret = spi_w8r16be(st->us, ADE7759_READ_REG(reg_address)); if (ret < 0) { dev_err(&st->us->dev, "problem when reading 16 bit register 0x%02X", reg_address); @@ -94,7 +94,6 @@ static int ade7759_spi_read_reg_16(struct device *dev, } *val = ret; - *val = be16_to_cpup(val); return 0; }
