From 2096b956d24c4b5950b808fc23b218425d79ebb1 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Tue, 1 May 2007 23:26:28 +0200 Subject: i2c: Shrink struct i2c_client This shrinks the size of "struct i2c_client" by 40 bytes: - Substantially shrinks the string used to identify the chip type - The "flags" don't need to be so big - Removes some internal padding It also adds kerneldoc for that struct, explaining how "name" is really a chip type identifier; it's otherwise potentially confusing. Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name and for i2c_adapter.name, this needed to affect i2c_adapter too. The adapters which used that symbol now use the more-obviously-correct idiom of taking the size of that field. JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to avoid wasting space in padding.
