Subject: ARM: 6637/1: Make the argument to virt_to_phys() "const volatile"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=05b112ff98070dc1f3293e8cd8e4c6f468d1084a;p=linux-beck.git

ARM: 6637/1: Make the argument to virt_to_phys() "const volatile"

Changing the virt_to_phys() argument to "const volatile void *" avoids
compiler warnings in some situations where this function is used.
