[PATCH 2/4] thermal: k3_j72xx_bandgap: Use kcalloc() instead of kzalloc()

From: Lukasz Luba
Date: Mon Feb 24 2025 - 12:38:26 EST


According to the latest recommendations, kcalloc() should be used instead
of kzalloc() with multiplication (which might overflow).
Switch to this new scheme and use more safe kcalloc().

No functional impact changes.
