memremap() is declared in linux/io.h, not in asm/io.h, so we should
include that header to avoid build errors:
drivers/platform/x86/dcdbas.c: In function 'dcdbas_check_wsmt':
drivers/platform/x86/dcdbas.c:572:15: error: implicit declaration of function 'memremap'; did you mean 'ioremap'? [-Werror=implicit-function-declaration]
eps_buffer = memremap(eps->smm_comm_buff_addr, remap_size, MEMREMAP_WB);
^~~~~~~~
ioremap
drivers/platform/x86/dcdbas.c:572:61: error: 'MEMREMAP_WB' undeclared (first use in this function)
eps_buffer = memremap(eps->smm_comm_buff_addr, remap_size, MEMREMAP_WB);
^~~~~~~~~~~
drivers/platform/x86/dcdbas.c:572:61: note: each undeclared identifier is reported only once for each function it appears in
drivers/platform/x86/dcdbas.c: In function 'dcdbas_exit':
