Subject: [PATCH 38/47] MIPS: ath79: use a helper function for USB resource initialization
|
|
|
|
This improves code readability, and ensures that
|
|
all resource fields will be initialized correctly.
|
|
Additionally, it helps to reduce the size of the
|
|
kernel image by using uninitialized resource
|
|
variables.
