firmware/imx-dsp: Fix use_after_free in imx_dsp_setup_channels()

2023-11-02T08:35:25+00:00

[ Upstream commit 1558b1a8dd388f5fcc3abc1e24de854a295044c3 ] dsp_chan->name and chan_name points to same block of memory, because dev_err still needs to be used it,so we need free it's memory after use to avoid use_after_free.

firmware: imx: scu-pd: Update comments for single global power domain

2021-03-29T00:59:33+00:00
