staging: most: usb: use correct error codes

This patch uses the -EINVAL return code where -EFAULT is wrongly being used. Signed-off-by: Christian Gromm Reported-by: Dan Carpenter Link: https://lore.kernel.org/r/1590570387-27069-9-git-send-email-christian.gromm@microchip.com Signed-off-by: Greg Kroah-Hartman

staging: most: usb: replace code to calculate array index

2020-05-27T10:26:12Z

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.

staging: most: usb: don't use error path to exit function on success

2020-05-27T10:26:12Z

This patch makes it transparent whether the function is exiting with an error or successful. Signed-off-by: Christian Gromm Reported-by: Dan Carpenter Link: https://lore.kernel.org/r/1590570387-27069-7-git-send-email-christian.gromm@microchip.com Signed-off-by: Greg Kroah-Hartman

staging: most: usb: move allocation of URB out of critical section

2020-05-27T10:24:46Z

This patch puts the call to usb_alloc_urb() before the critical section starts that is protected with the io_mutex lock. This is to make the section as short as possible and to use the regular GFP_KERNEL flag.

staging: most: usb: return 0 instead of variable

2020-05-27T10:24:46Z
