From: Geert Uytterhoeven Date: Mon, 8 Aug 2011 11:08:19 +0000 (+0200) Subject: TPM: TCG_ATMEL should depend on HAS_IOPORT X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5ce5ed35939ece8a9c7e0f10c7f3d5bc000c6b64;p=openwrt%2Fstaging%2Fblogic.git TPM: TCG_ATMEL should depend on HAS_IOPORT On m68k, I get: drivers/char/tpm/tpm_atmel.h: In function ‘atmel_get_base_addr’: drivers/char/tpm/tpm_atmel.h:129: error: implicit declaration of function ‘ioport_map’ drivers/char/tpm/tpm_atmel.h:129: warning: return makes pointer from integer without a cast The code in tpm_atmel.h supports PPC64 (using the device tree and ioremap()) and "anything else" (using ioport_map()). However, ioportmap() is only available on platforms that set HAS_IOPORT. Although PC64 seems to have HAS_IOPORT, a "depends on HAS_IOPORT" should work, but I think it's better to expose the special PPC64 handling explicit using "depends on PPC64 || HAS_IOPORT".
