I do think that the types being assigned should correct with respect to the API definition even if it fits in this case. >> >> Signed-off-by: Nicholas Mc Guire <hofrat@xxxxxxxxx> >> --- >> >> Aside from the fixup of the wait_for_completion_timeout handling >> a minor coding style issue in the else branch was fixed - the {} is >> not needed for the one-line body. > > If one of the branches of a conditional statement has braces the other > branches should also have braces. This is documented in > Documentation/CodingStyle. my bad - it is not uncommon to be asymetric - but you are right that Chapter 3 states it should not be asymetric in this case - will remove that. given the botched braces this needs to be redone - let me know if moving it into the condition is ok (its not uncommon) or if an additional variable of type unsigned long is the prefered solution. thanks for your review ! thx! hofrat -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
