Subject: ALSA: Close holes in struct snd_pcm_hw_rule
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d16efa0626bfd11157d4a622a24aaae98435f26d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: Close holes in struct snd_pcm_hw_rule

On a 64-bit system there are two 32-bit holes due to the alignment of 64-bit
fields. Reordering things slightly gets rid of those holes, reducing the
size of the struct by 17% percent of its original size.
