Subject: crypto: omap-sham - shrink the internal buffer size
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=182e283f3e550d70ba5b7e6be66ea74726646166;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

crypto: omap-sham - shrink the internal buffer size

The current internal buffer size is way too large for crypto core, so
shrink it to be smaller. This makes the buffer to fit into the space
reserved for the export/import buffers also.
