Subject: rtl8xxxu: Implement generic init_queue_reserved_page() function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=89c2a097df34362a5e8373749a2f81ca2503b598;p=linux-beck.git

rtl8xxxu: Implement generic init_queue_reserved_page() function

Longer term we should switch all the chips over to use this function
instead of the random chip specific ifdef hacks.
