Yang Yingliang ee86d0bad8 iio: accel: kxcjk-1013: Fix possible memory leak in probe and remove 
commit 70c9774e180d151abaab358108e3510a8e615215 upstream.

When ACPI type is ACPI_SMO8500, the data->dready_trig will not be set, the
memory allocated by iio_triggered_buffer_setup() will not be freed, and cause
memory leak as follows:

unreferenced object 0xffff888009551400 (size 512):
  comm "i2c-SMO8500-125", pid 911, jiffies 4294911787 (age 83.852s)
  hex dump (first 32 bytes):
    02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
    00 00 00 00 00 00 00 00 20 e2 e5 c0 ff ff ff ff  ........ .......
  backtrace:
    [<0000000041ce75ee>] kmem_cache_alloc_trace+0x16d/0x360
    [<000000000aeb17b0>] iio_kfifo_allocate+0x41/0x130 [kfifo_buf]
    [<000000004b40c1f5>] iio_triggered_buffer_setup_ext+0x2c/0x210 [industrialio_triggered_buffer]
    [<000000004375b15f>] kxcjk1013_probe+0x10c3/0x1d81 [kxcjk_1013]

Fix it by remove data->dready_trig condition in probe and remove.
