Subject: [PATCH] phy: phy-brcm-usb: Constify static structs
|
|
|
|
A number of structs were not modified and can therefore be made const
|
|
to allow the compiler to put them in read-only memory.
|
|
|
|
In order to do so, update a few functions that don't modify there input
|
|
to take pointers to const.
|
|
|
|
Before:

|
text data bss dec hex filename

After:
