charset="utf-8" From: Lad Prabhakar Refactor error handling in the ov5645_probe() function by replacing multiple dev_err() calls with dev_err_probe(). - Note that during this process, the error string "external clock frequency %u is not supported" was replaced with "unsupported xclk frequency %u" to ensure it wraps at 80 columns. - Additionally, the error string for control initialization failure was changed from "%s: control initialization error %d\n" to "failed to add controls\n" as there is no need to print the function name and error code in the string, since dev_err_probe() already provides this information.
