When the optee driver is compiled into the kernel while the i2c core is configured as a module, the i2c symbols are not available.
This commit addresses the situation by disabling the i2c support for this use case while allowing it in all other scenarios: i2c=y, optee=y i2c=m, optee=m i2c=y, optee=m i2c=m, optee=y (not supported) Reported-by: kernel test robot <l...@intel.com> Signed-off-by: Jorge Ramirez-Ortiz <jo...@foundries.io> --- This patch applies on top of https://git.linaro.org/people/jens.wiklander/linux-tee.git/tag/?h=optee-i2c-for-v5.10 drivers/tee/optee/rpc.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/tee/optee/rpc.c b/drivers/tee/optee/rpc.c index 64a206c56264..96e91d5f0a86 100644 --- a/drivers/tee/optee/rpc.c +++ b/drivers/tee/optee/rpc.c @@ -51,6 +51,7 @@ static void handle_rpc_func_cmd_get_time(struct optee_msg_arg *arg) } #if IS_ENABLED(CONFIG_I2C) +#if !defined(CONFIG_I2C_MODULE) || defined(CONFIG_OPTEE_MODULE) static void handle_rpc_func_cmd_i2c_transfer(struct tee_context *ctx, struct optee_msg_arg *arg) { @@ -140,6 +141,7 @@ static void handle_rpc_func_cmd_i2c_transfer(struct tee_context *ctx, arg->ret = TEEC_ERROR_NOT_SUPPORTED; } #endif +#endif static struct wq_entry *wq_entry_get(struct optee_wait_queue *wq, u32 key) { -- 2.17.1
