Subject: crypto: caam/qi - fix compilation with CONFIG_DEBUG_FORCE_WEAK_PER_CPU=y
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1ed289f7b78c34565a33dbe6f8c482e71f493934;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

crypto: caam/qi - fix compilation with CONFIG_DEBUG_FORCE_WEAK_PER_CPU=y

caam/qi driver fails to compile when CONFIG_DEBUG_FORCE_WEAK_PER_CPU=y.
Fix it by making the offending local per_cpu variable global.
