mm,fs,dax: mark dax_iomap_pmd_fault as const
The two alternative implementations of dax_iomap_fault have different prototypes, and one of them is obviously wrong as seen from this build warning: fs/dax.c: In function 'dax_iomap_fault': fs/dax.c:1462:35: error: passing argument 2 of 'dax_iomap_pmd_fault' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers] This marks the argument 'const' as in all the related functions. Fixes: a2d581675d48 ("mm,fs,dax: change ->pmd_fault to ->huge_fault") Link: http://lkml.kernel.org/r/20170227203349.3318733-1-arnd@arndb.de Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
