Subject: tpm: substitute deprecated uint<x>_t types with their u<x> equivalent
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=b9804e5bf36351b77cf354a81304657a895c9f0f;p=u-boot.git

tpm: substitute deprecated uint<x>_t types with their u<x> equivalent

Fix following checkpatch.pl issues in TPM-related code:

    CHECK: Prefer kernel type 'u8' over 'uint8_t'
    CHECK: Prefer kernel type 'u16' over 'uint16_t'
    CHECK: Prefer kernel type 'u32' over 'uint32_t'
