Title
iio: fix memory leak in iio_device_register_eventset()
Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: fix memory leak in iio_device_register_eventset()
When iio_device_register_sysfs_group() returns failed,
iio_device_register_eventset() needs to free attrs array.
Otherwise, kmemleak would scan & report memory leak as below:
unreferenced object 0xffff88810a1cc3c0 (size 32):
comm "100-i2c-vcnl302", pid 728, jiffies 4295052307 (age 156.027s)
backtrace:
__kmalloc+0x46/0x1b0
iio_device_register_eventset at drivers/iio/industrialio-event.c:541
__iio_device_register at drivers/iio/industrialio-core.c:1959
