[PATCH] usb: typec: ucsi: fix Clang -Wsign-conversion warning

[Qasim Ijaz <qasdev00@gmail.com>]

debugfs.c emits the following warnings when compiling with the -Wsign-conversion flag with clang 15:

drivers/usb/typec/ucsi/debugfs.c:58:27: warning: implicit conversion changes signedness: 'int' to 'u32' (aka 'unsigned int') [-Wsign-conversion]
                ucsi->debugfs->status = ret;
                                      ~ ^~~
drivers/usb/typec/ucsi/debugfs.c:71:25: warning: implicit conversion changes signedness: 'u32' (aka 'unsigned int') to 'int' [-Wsign-conversion]
                return ucsi->debugfs->status;
                ~~~~~~ ~~~~~~~~~~~~~~~^~~~~~
                
During ucsi_cmd() we see:

	if (ret < 0) {
		ucsi->debugfs->status = ret;
		return ret;
	}
	
But "status" is u32 meaning unsigned wrap-around occurs when assigning a value which is < 0 to it, this obscures the real status.

To fix this make the "status" of type int since ret is also of type int.
