There was an exception in which the uC version verification was being done directly elsewhere. While at it, the Version Register hardcoded value was replaced with a pre-existing constant in the driver. This patch adds rf69_get_chip_version function to rf69.c Additionally, the patch below must be applied first as it was sent before and touches the same file. https://lore.kernel.org/lkml/20220103222334.GA6814@mail.google.com/ Signed-off-by: Paulo Miguel Almeida --- drivers/staging/pi433/pi433_if.c | 4 +--- drivers/staging/pi433/rf69.c | 8 ++++++++ drivers/staging/pi433/rf69.h | 1 + 3 files changed, 10 insertions(+), 3 deletions(-) diff --git a/drivers/staging/pi433/pi433_if.c b/drivers/staging/pi433/pi433_if.c index 29bd37669059..a19afda5b188 100644 --- a/drivers/staging/pi433/pi433_if.c +++ b/drivers/staging/pi433/pi433_if.c @@ -1116,9 +1116,7 @@ static int pi433_probe(struct spi_device *spi) spi->mode, spi->bits_per_word, spi->max_speed_hz); /* Ping the chip by reading the version register */ - retval = spi_w8r8(spi, 0x10); - if (retval < 0) - return retval; + retval = rf69_get_chip_version(spi); switch (retval) { case 0x24: diff --git a/drivers/staging/pi433/rf69.c b/drivers/staging/pi433/rf69.c index d64df072d8e8..1516012f9bb7 100644 --- a/drivers/staging/pi433/rf69.c +++ b/drivers/staging/pi433/rf69.c @@ -102,6 +102,14 @@ static inline int rf69_read_mod_write(struct spi_device *spi, u8 reg, /*-------------------------------------------------------------------------*/ +int rf69_get_chip_version(struct spi_device *spi) +{ + int retval; + + retval = rf69_read_reg(spi, REG_VERSION); + return retval; +} + int rf69_set_mode(struct spi_device *spi, enum mode mode) { static const u8 mode_map[] = { diff --git a/drivers/staging/pi433/rf69.h b/drivers/staging/pi433/rf69.h index b648ba5fff89..ca9b75267840 100644 --- a/drivers/staging/pi433/rf69.h +++ b/drivers/staging/pi433/rf69.h @@ -17,6 +17,7 @@ #define FIFO_SIZE 66 /* bytes */ #define FIFO_THRESHOLD 15 /* bytes */ +int rf69_get_chip_version(struct spi_device *spi); int rf69_set_mode(struct spi_device *spi, enum mode mode); int rf69_set_data_mode(struct spi_device *spi, u8 data_mode); int rf69_set_modulation(struct spi_device *spi, enum modulation modulation); -- 2.25.4
