From: Malcolm Priestley Date: Thu, 26 Sep 2013 17:52:10 +0000 (+0100) Subject: staging: vt6656: rxtx.c s_vGenerateTxParameter Create vnt_mic_hdr structure X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f0e0d5051cccfc8ccfae02a40012c1a35c25c05a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging: vt6656: rxtx.c s_vGenerateTxParameter Create vnt_mic_hdr structure Create double pointer to pass back vnt_mic_hdr address position of relevant structure if need_mic is more than 0. Otherwise it is NULL. This replaces the pMICHDR void pointer with struct vnt_mic_hdr and assignments in the calling functions.
