drviers: mipi_dbi: mipi_dbi_bitbang: fix 16-bit data_gpios exceed error (535c40d6) · Commits · Wenxi XU / zephyr

For a 16-bit data bus, "DT_INST_PROP_LEN(n, data_gpios)" returns 16 which is equals "MIPI_DBI_MAX_DATA_BUS_WIDTH(16)". As a result, the assertion will always be triggered. Use a "<=" condition for the assertion instead. Signed-off-by:
