But this driver defines the table as a single struct spi_device_id and sets .id_table to a pointer to this struct. But spi_match_id() has a loop that iterates while the struct spi_device_id .name[0] is not NULL, so not having a sentinel can cause a NULL pointer deference error. This patch defines the SPI id table correctly as all other SPI drivers do. Signed-off-by: Javier Martinez Canillas Signed-off-by: David S.
