media: staging: media: atomisp: init high & low varsfixes
Fix a compiler warning: include/linux/dev_printk.h: In function 'ov2680_probe': include/linux/dev_printk.h:144:31: warning: 'high' may be used uninitialized [-Wmaybe-uninitialized] 144 | dev_printk_index_wrap(_dev_err, KERN_ERR, dev, dev_fmt(fmt), ##__VA_ARGS__) | ^~~~~~~~ In function 'ov2680_detect', inlined from 'ov2680_s_config' at drivers/staging/media/atomisp/i2c/atomisp-ov2680.c:468:8, inlined from 'ov2680_probe' at drivers/staging/media/atomisp/i2c/atomisp-ov2680.c:647:8: drivers/staging/media/atomisp/i2c/atomisp-ov2680.c:376:13: note: 'high' was declared here 376 | u32 high, low; | ^~~~ 'high' is indeed uninitialized after the ov_read_reg8() call failed, so there is no point showing the value. Just say that the read failed. But low can also be used uninitialized later, so just make it more robust and properly zero the high and low variables.
