Subject: fscrypt: fix build with pre-4.6 gcc versions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b4edfb10398cae62114f95201bdd2e997319920;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

fscrypt: fix build with pre-4.6 gcc versions

gcc versions prior to 4.6 require an extra level of braces when using a
designated initializer for a member in an anonymous struct or union.
This caused a compile error with the 'struct qstr' initialization in
__fscrypt_encrypt_symlink().

Fix it by using QSTR_INIT().
