All the while() loops that check for the SPI transfer to be complete have the semi-colon immediately after the closing parenthesis. This both causes a compiler warning of "warning: suggest a space before ';' or explicit braces around empty body in 'while' statement", and is considered a less-than-ideal programming practice. This patch breaks the semi-colon on to the next line, both eliminating the compiler error and making the code more readable. In all probability the test should be moved into a macro or a inlineable sub-routine.
