'rc' is known to be 0 here.
Initialize 'rc' with the expected error code before using it.
I would prefer:
"In cxl_add_chardev(), if the call to device_create() fails, we print
the error message before 'rc' is set correctly, and therefore always
print 0. Move the error message after setting 'rc'."
While at it, avoid the affectation of 'rc' in a 'if' to make things more
obvious and linux style.
I strongly agree with this, some of the other cxl developers don't but
they are wrong :)
