here, and has just been applied to linux-media master.

media: imx334: 'ret' is uninitialized, should have been PTR_ERR()
Fix this compiler warning:
drivers/media/i2c/imx334.c: In function 'imx334_parse_hw_config':
include/linux/dev_printk.h:112:2: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]
112 | _dev_err(dev, dev_fmt(fmt), ##__VA_ARGS__)
| ^~~~~~~~
drivers/media/i2c/imx334.c:783:6: note: 'ret' was declared here
783 | int ret;
