Tetsuyuki Kobayashi 7a65768903 i2c: sh_i2c: bugfix: i2c probe command does not work ... This is regression of commit 2035d77d i2c: sh_i2c: Update to new CONFIG_SYS_I2C framework Before commit 2035d77d, i2c probe command works properly on kzm9g board. KZM-A9-GT# i2c probe Valid chip addresses: 0C 12 1D 32 39 3D 40 60 After commit 2035d77d, i2c probe command does not work. KZM-A9-GT# i2c probe Valid chip addresses: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F sh_i2c_probe() calls sh_i2c_read(), but read length is 0. So acutally it does not read device at all. This patch prepares dummy buffer and read data into it.
