Subject: [PATCH v2 04/13] platform/x86: i2c-mutli-instantiate: Defer probe when no adapter found
Date: Mon, 26 Nov 2018 17:08:49 +0200 [thread overview]
Message-ID: <20181126150858.16901-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20181126150858.16901-1-andriy.shevchenko@linux.intel.com>
Likewise the rest of the i2c_acpi_new_device() users, defer the probe
of the i2c-multi-intantiate driver in case adapter is not yet found.
