aes: make apply_cbc_chain_data non-static
Tegra's crypto.c uses apply_cbc_chain_data() to sign the warm restart code. This function was recently moved into the core aes.c and made static, which prevents the Tegra code from compiling. Make it public again to avoid the compile errors: arch/arm/cpu/tegra20-common/crypto.c: In function ‘sign_object’: arch/arm/cpu/tegra20-common/crypto.c:74:3: warning: implicit declaration of function ‘apply_cbc_chain_data’ [-Wimplicit-function-declaration] arch/arm/cpu/built-in.o: In function `sign_object': .../arch/arm/cpu/tegra20-common/crypto.c:74: undefined reference to `apply_cbc_chain_data' .../arch/arm/cpu/tegra20-common/crypto.c:78: undefined reference to `apply_cbc_chain_data' Fixes: 6e7b9f4fa0ae ("aes: Move the AES-128-CBC encryption function to common code") Signed-off-by: Stephen Warren <> Reviewed-by: Simon Glass <> Acked-by: Marek Vasut <>
