NTB: fix 32-bit compiler warning
resource_size_t may be 32-bit wide on some architectures, which causes this warning when building the NTB code: drivers/ntb/ntb_transport.c: In function 'ntb_transport_link_work': drivers/ntb/ntb_transport.c:828:46: warning: right shift count >= width of type [-Wshift-count-overflow] The warning is harmless but can be avoided by using the upper_32_bits() macro. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: e26a5843f7f5 ("NTB: Split ntb_hw_intel and ntb_transport drivers") Signed-off-by: Jon Mason <jdmason@kudzu.us>
