When CONFIG_PM=n, make sure that the usb_[unlocked_][en/dis]able_lpm declarations are visible in include/linux/usb.h, and exported from drivers/usb/core/hub.c. Before this patch, if CONFIG_USB_SUSPEND was turned off, it would cause build errors: drivers/usb/core/hub.c: In function 'usb_disable_lpm': drivers/usb/core/hub.c:3394:2: error: implicit declaration of function 'usb_enable_lpm' [-Werror=implicit-function-declaration] drivers/usb/core/hub.c: At top level: drivers/usb/core/hub.c:3424:6: warning: conflicting types for 'usb_enable_lpm' [enabled by default] drivers/usb/core/hub.c:3394:2: note: previous implicit declaration of 'usb_enable_lpm' was here drivers/usb/core/driver.c: In function 'usb_probe_interface': drivers/usb/core/driver.c:339:2: error: implicit declaration of function 'usb_unlocked_disable_lpm' [-Werror=implicit-function-declaration] drivers/usb/core/driver.c:364:3: error: implicit declaration of function 'usb_unlocked_enable_lpm' [-Werror=implicit-function-declaration] drivers/usb/core/message.c: In function 'usb_set_interface': drivers/usb/core/message.c:1314:2: error: implicit declaration of function 'usb_disable_lpm' [-Werror=implicit-function-declaration] drivers/usb/core/message.c:1323:3: error: implicit declaration of function 'usb_enable_lpm' [-Werror=implicit-function-declaration] drivers/usb/core/message.c:1368:2: error: implicit declaration of function 'usb_unlocked_enable_lpm' [-Werror=implicit-function-declaration] Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Reported-by: Chen Peter-B29397 <B29397@freescale.com> |
