When compiling the tegra-oc-event driver with Linux v6.13 the build
fails with the following error:
drivers/thermal/tegra234-oc-event.c:127:48: error: missing braces around
initialiser [-Werror=missing-braces]
127 | static const struct attribute_group oc1_data = {
| ^
The 'NULL' initialiser is not needed in the above structure because it
is not any array. Fix the build for Linux v6.13 by removing the NULL
initialisers from the appropriate structure declarations.

Building the tegra-oc-event driver generates the following warning ...

Fix this by correcting the type for the soc_data structure member.

SOC_THERM is the primary hardware component of Tegra on-die thermal
management strategies. SOC_THERM includes the function of
externally-signaled event detection (SOC_THERM_edp) which centralizes
a few mechanisms for detecting and responding to externally signaled
electrical events, such as overcurrent events, undervoltage events, and
so on. These are known as "OC alarms" because they often indicate an
overcurrent event.
The Jetson Module's on-board power monitor INA3221 is configured to
trigger CPU/GPU hardware clock throttling via Tegra234 SOCTHERM_OC when
the Module input current exceeds the preprogrammed overcurrent threshold
to keep Module power consumption within the TDP power budget.
CPU/GPU performance may drop when hardware clock throttling occurs.
To allow the user to infer whether the performance degradation is
related to the overcurrent event, the Tegra234 OC event driver is
implemented which sends a Message ReQuest (MRQ) to the BPMP firmware to
provide information regarding the overcurrent enable state and the event
count to userspace via the hwmon sysfs interface.
