Subject: [media] af9015: Don't use dynamic static allocation
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=65e2f1cb3fe0f0630834b9517ba8f631936f325c;p=linux-beck.git

[media] af9015: Don't use dynamic static allocation

Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
	drivers/media/usb/dvb-usb-v2/af9015.c:433:1: warning: 'af9015_eeprom_hash' uses dynamic stack allocation [enabled by default]
In this specific case, it is a gcc bug, as the size is a const, but
it is easy to just change it from const to a #define, getting rid of
the gcc warning.
