The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From e825070f697abddf3b9b0a675ed0ff1884114818 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 17 Dec 2019 19:10:38 +0200 Subject: iio: st_gyro: Correct data for LSM9DS0 gyro The commit 41c128cb25ce ("iio: st_gyro: Add lsm9ds0-gyro support") assumes that gyro in LSM9DS0 is the same as others with 0xd4 WAI ID, but datasheet tells slight different story, i.e. the first scale factor for the chip is 245 dps, and not 250 dps. Correct this by introducing a separate settings for LSM9DS0.
