From: Jean Delvare Date: Fri, 2 Oct 2009 08:47:08 +0000 (-0300) Subject: V4L/DVB (13233): i2c_board_info can be local X-Git-Tag: v2.6.33-rc1~338^2~201 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=43e16ea241cab1f4d4206307b2f6eacbaf4dc335;p=~shefty%2Frdma-dev.git V4L/DVB (13233): i2c_board_info can be local Recent fixes to the em28xx and saa7134 drivers have been overzealous. While the ir-kbd-i2c platform data indeed needs to be persistent, the struct i2c_board_info doesn't, as it is only used by i2c_new_device(). So revert a part of the original fixes, to save some memory.
