msm_actuator.c中i2c操作造成msm_sensor.c的i2c操作超时退出问题。

MSM8916的平台在msm_actuator.c中添加调用msm_CAMERA_cci_I2C_write_seq发命令控制camera对焦，有时会造成msm_sensor.c中调用msm_camera_cci_i2c_write_table失败，提示等待超时，之后msm_camera_cci_i2c_write_seq也失败了，log如下：msm_camera_cci_i2c_write_seq--success--rc = 0
msm_cci_i2c_write: wait_for_completion_timeout 617
msm_cci_flush_queue:107 wait timeout
msm_camera_cci_i2c_write_table: line 201 rc = -110
msm_cci_i2c_write: wait_for_completion_timeout 617
msm_cci_flush_queue:107 wait timeout

msm_camera_cci_i2c_write_seq--success--rc = 0
msm_cci_i2c_write: wait_for_completion_timeout 617
msm_cci_flush_queue:107 wait timeout
msm_camera_cci_i2c_write_table: line 201 rc = -110
msm_cci_i2c_write: wait_for_completion_timeout 617
msm_cci_flush_queue:107 wait timeout

msm_camera_cci_i2c_write_seq--failed--rc = -110
msm_cci_i2c_write: wait_for_completion_timeout 617
msm_cci_flush_queue:107 wait timeout

请问有哪位大牛了解这个，请帮忙指点一下，非常感谢！

会不会是打log太多了?

已解决。在出现msm_camera_cci_i2c_write_table失败时，测波形发现SDL一直为低，于是在通讯失败时软件上操作i2c的gpio进行了复位，然后又可以恢复通讯了。
