Subject: fbdev: omap2: connector-dvi: use of_get_i2c_adapter_by_node interface
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ad38cc5f6d4f2c74ed69e2c017691e428549b2bd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

fbdev: omap2: connector-dvi: use of_get_i2c_adapter_by_node interface

This change is needed to properly lock I2C bus driver, which serves DDC.

Prior to this change i2c_put_adapter() is misused, which may lead to
an overflow over zero of I2C bus driver user counter.
