ASoC: amd: acp: Fix incorrect retrival of acp_chip_info
[ Upstream commit d7871f400cad1da376f1d7724209a1c49226c456 ]
Use dev_get_drvdata(dev->parent) instead of dev_get_platdata(dev)
to correctly obtain acp_chip_info members in the acp I2S driver.
Previously, some members were not updated properly due to incorrect
data access, which could potentially lead to null pointer
dereferences.
This issue was missed in the earlier commit
("ASoC: amd: acp: Fix NULL pointer deref in acp_i2s_set_tdm_slot"),
which only addressed set_tdm_slot(). This change ensures that all
relevant functions correctly retrieve acp_chip_info, preventing
further null pointer dereference issues.
Fixes: e3933683b25e ("ASoC: amd: acp: Remove redundant acp_dev_data structure")
