Subject: i2c: Use __weak instead of __attribute__((weak, alias))
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=2515d8437bf3a4415d3354d01e37f07d922250e2;p=u-boot.git

i2c: Use __weak instead of __attribute__((weak, alias))

Use __weak from linux/compiler.h instead of __attribute__((weak, alias))
to define overridable function. This patch is intended as a cleanup patch
to bring some consistency into the code.
