Subject: thermal: k3_j72xx_bandgap: Use kcalloc() instead of kzalloc()
X-Git-Tag: v6.15-rc1~190^2^3~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=83c34f5099bf38917b8518404f4ff32d5878fa8d;p=thirdparty%2Fkernel%2Flinux.git

thermal: k3_j72xx_bandgap: Use kcalloc() instead of kzalloc()

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.
