Subject: openrisc: Remove unused tlb_init function
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c03b12a68f4a9c91e563c909b25bd28b8f1b9414;p=linux.git

openrisc: Remove unused tlb_init function

When compiling with W=1 enabling -Wmissing-prototypes the compiler
warns:

  arch/openrisc/mm/tlb.c:188:13: error: no previous prototype for 'tlb_init' [-Werror=missing-prototypes]

This function is not implemented or used so remove it.
