Analyze and fix the following issue in the Linux kernel code: [PATCH] powerpc: Fix sound driver use of i2c
Problem Details: The PowerMac sound drivers used to rely on a "bug" of the i2c-keywest driver that implemented I2C_SMBUS_BLOCK_DATA incorrectly, that is it did what I2C_SMBUS_I2C_BLOCK_DATA should have done. The new i2c-powermac driver that replaces keywest has this bug fixed, thus the sound drivers must be fixed too. ...

Analyze and fix the following issue in the Linux kernel code: [MIPS] TX49x7: Fix reporting of the CPU name and PCI clock
Problem Details: I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips... Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937"); an...
