From e914cfdf12ab1a3f7339c95a65c8b5743c951fa6 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Mon, 10 Feb 2020 15:26:00 +0200 Subject: [PATCH] iio: gyro: adis16136: initialize adis_data statically This change overrides commit 380b107bbf944 ("iio: adis: Introduce timeouts structure"). It removes the memory allocation and moves the 'adis_data' information to be static on the chip_info struct. This also adds a timeout structure to ADIS16334, since it was initially omitted. This was omitted (by accident) when the change was done.
