2020-05-27staging: most: usb: replace code to calculate array indexChristian Gromm
This patch removes the expression that makes use of a priori knowledge about channel numbers to calculate an array index. The expression 'peer = 1 - channel' utilizes the fact that an USB interface that operates on the asynchronous data of the Network only has two endpoints. Hence, channel being 0 or 1. The replacement is more simple and less confusing when reading the code.
