From c8917b8ff09e8a4d6ef77e32ce0052f7158baa1f Mon Sep 17 00:00:00 2001 From: Mauro Rossi Date: Mon, 22 Jul 2019 07:55:36 +0200 Subject: [PATCH] firmware: fix build errors in paged buffer handling code fw_{grow,map}_paged_buf() need to be defined as static inline when CONFIG_FW_LOADER_PAGED_BUF is not enabled, infact fw_free_paged_buf() is also defined as static inline when CONFIG_FW_LOADER_PAGED_BUF is not enabled. Fixes the following mutiple definition building errors for Android kernel: drivers/base/firmware_loader/fallback_efi.o: In function `fw_grow_paged_buf': fallback_efi.c:(.text+0x0): multiple definition of `fw_grow_paged_buf' drivers/base/firmware_loader/main.o:(.text+0x73b): first defined here drivers/base/firmware_loader/fallback_efi.o: In function `fw_map_paged_buf': fallback_efi.c:(.text+0xf): multiple definition of `fw_map_paged_buf' drivers/base/firmware_loader/main.o:(.text+0x74a): first defined here [ slightly corrected the patch description -- tiwai ] Fixes: 5342e7093ff2 ("firmware: Factor out the paged buffer handling code") Fixes: 82fd7a8142a1 ("firmware: Add support for loading compressed files") Signed-off-by: Mauro Rossi Signed-off-by: Takashi Iwai Link: https://lore.kernel.org/r/20190722055536.15342-1-tiwai@suse.de Signed-off-by: Greg Kroah-Hartman --- drivers/base/firmware_loader/firmware.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/base/firmware_loader/firmware.h b/drivers/base/firmware_loader/firmware.h index 7048a41973ed..842e63f19f22 100644 --- a/drivers/base/firmware_loader/firmware.h +++ b/drivers/base/firmware_loader/firmware.h @@ -141,8 +141,8 @@ int fw_grow_paged_buf(struct fw_priv *fw_priv, int pages_needed); int fw_map_paged_buf(struct fw_priv *fw_priv); #else static inline void fw_free_paged_buf(struct fw_priv *fw_priv) {} -int fw_grow_paged_buf(struct fw_priv *fw_priv, int pages_needed) { return -ENXIO; } -int fw_map_paged_buf(struct fw_priv *fw_priv) { return -ENXIO; } +static int fw_grow_paged_buf(struct fw_priv *fw_priv, int pages_needed) { return -ENXIO; } +static int fw_map_paged_buf(struct fw_priv *fw_priv) { return -ENXIO; } #endif #endif /* __FIRMWARE_LOADER_H */
