From: Andrey Smirnov Date: Fri, 13 Feb 2015 07:58:41 +0000 (-0800) Subject: IIO: si7020: Allocate correct amount of memory in devm_iio_device_alloc X-Git-Tag: v3.19.2~110 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dc77d1f2ff85e75ff2c9ac3ec462116468f98a63;p=thirdparty%2Fkernel%2Fstable.git IIO: si7020: Allocate correct amount of memory in devm_iio_device_alloc commit e01becbad300712a28f29b666e685536f45e83bc upstream. Since only a pointer to struct i2c_client is stored in a private area of IIO device created by the driver there's no need to allocate sizeof(struct i2c_client) worth of storage. Pushed to stable as this is linked to the revert patch previously. Without this followup the original patch looks sensible.
