Subject: ieee802154: ca8210: Fix a potential NULL pointer dereference
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f00c2987bfdde69c6eb27b5547d222beb5bc7552;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ieee802154: ca8210: Fix a potential NULL pointer dereference

'spi' is known to be NULL, so we dereference a NULL pointer here.
Use 'pr_crit()' instead of 'dev_crit()' to report the message.
