Subject: [media] Technisat SkyStar USB HD,(DVB-S/S2) too much URBs for arm devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3139f43f8eca4d3a8a0ffe3b0b9cd8ebe0e3be95;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] Technisat SkyStar USB HD,(DVB-S/S2) too much URBs for arm devices

Using 8 URBs results in a consecutive buffer allocation of too much
memory for some arm devices.
As we use isochronuous transfers the number of URBs can be reduced
without risking data-loss.
