[PATCH v6 1/3] drm/panel: Fix IS_ERR() vs NULL check in nt35950_probe()

The mipi_dsi_device_register_full() returns an ERR_PTR() on failure, we should use IS_ERR() to check the return value. By the way, use dev_err_probe instead of dev_err to print the error code. Fixes: 623a3531e9cf ("drm/panel: Add driver for Novatek NT35950 DSI DriverIC panels") Signed-off-by:
