Summary
In the Linux kernel, the following vulnerability has been resolved: iio: adis16475: fix deadlock on frequency set With commit 39c024b51b560 ("iio: adis16475: improve sync scale mode handling"), two deadlocks were introduced: 1) The call to 'adis_write_reg_16()' was not changed to it's unlocked version. 2) The lock was not being released on the success path of the function. This change fixes both these issues.
