That\nallows for some simplifications in the code.\n\nTested on a Renesas Lager board (R-Car H2) doing a bunch of consecutive\ncommands. No spurious interrupts have been observed and the signals look\nexactly the same when visualized with sigrok.\n\nAccording to the docs, the ICE bit behaviour is the same since the beginning of\nthis driver (sh7722) for the migo-r board.\n\njacopo: can you please test this series while you work on migo-r anyhow? Thank\nyou a ton for that!\n\nLooking forward to other comments, as well...\n\n\nWolfram Sang (5):\n  i2c: sh_mobile: remove redundant initialization\n  i2c: sh_mobile: remove redundant deinitialization\n  i2c: sh_mobile: manually \"inline\" two short functions\n  i2c: sh_mobile: use direct writes when accessing ICE bit\n  i2c: sh_mobile: shorten exit of xfer routine\n\n drivers/i2c/busses/i2c-sh_mobile.c | 50 +++++++++-----------------------------\n 1 file changed, 12 insertions(+), 38 deletions(-)"
