From: Thomas Meyer Date: Thu, 17 Nov 2011 12:43:40 +0000 (+0000) Subject: CDC NCM: Use kzalloc rather than kmalloc followed by memset with 0 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c796984f2f1c528ac21220808525440d49413f8c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git CDC NCM: Use kzalloc rather than kmalloc followed by memset with 0 This considers some simple cases that are common and easy to validate Note in particular that there are no ...s in the rule, so all of the matched code has to be contiguous The semantic patch that makes this change is available in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.
