linux-toradex.git/drivers/cpufreq, branch v6.19-rc2 Linux kernel for Apalis and Colibri modules cpufreq: dt-platdev: Fix creating device on OPPv1 platforms 2025-12-16T13:59:30+00:00 Krzysztof Kozlowski krzysztof.kozlowski@oss.qualcomm.com 2025-12-10T05:17:19+00:00 0f5796dac1bb7e3b8a36eec54e3a2c6bf70aa414 Commit 6ea891a6dd37 ("cpufreq: dt-platdev: Simplify with of_machine_get_match_data()") broke several platforms which did not have OPPv2 proprety, because it incorrectly checked for device match data after first matching from "allowlist". Almost all of "allowlist" match entries do not have match data and it is expected to create platform device for them with empty data. Fix this by first checking if platform is on the allowlist with of_machine_device_match() and only then taking the match data. This duplicates the number of checks (we match against the allowlist twice), but makes the code here much smaller.

Commit 6ea891a6dd37 ("cpufreq: dt-platdev: Simplify with
of_machine_get_match_data()") broke several platforms which did not have
OPPv2 proprety, because it incorrectly checked for device match data
after first matching from "allowlist".  Almost all of "allowlist" match
entries do not have match data and it is expected to create platform
device for them with empty data.

Fix this by first checking if platform is on the allowlist with
of_machine_device_match() and only then taking the match data.  This
duplicates the number of checks (we match against the allowlist twice),
but makes the code here much smaller.

If CONFIG_OF is not enabled, of_match_node() is set as NULL and
qcom_cpufreq_ipq806x_match_list won't be used causing a compilation
warning.

Flag qcom_cpufreq_ipq806x_match_list as __maybe_unused to fix the
compilation warning.

While at it also flag as __initconst as it's used only in probe contest
and can be freed after probe.

This follows the pattern of the usual of_device_id variables.
